Butterfly Valve Bray S40

Батерфляй Bray S 40

Bray S40. The unique, two-part seat assembly consists of a resilient energizer (M) which is totally encapsulated by the RTFE* seat (N). The assembly is locked in the body recess by a full–faced seat retainer (O). This simple, reliable and proven combination results in many exclusive advantages, including:
• The energizer is completely isolated from all contact with the line media by the RTFE seat.
• Serrations in the seat retainer and body recess secure the seat assembly in place regardless of disc position.
• The full–faced retainer is bolted to the body, locking the seat in the correct position. The seat is secured even without the mating flange.
• The closely confined and well supported seat is energized by the disc and line pressure. The higher the pressure, the tighter the seal. In low pressure and vacuum applications, the energized seat offers superior sealing and longer service life than many other designs.
• Line media is sealed to zero leakage in both directions.
• The seat is self–adjusting for wear and temperature changes.
• Seat replacement is extremely easy – just remove the seat retainer, rotate the disc into the closed position and place a new seat assembly in the machined recess of the body. This simple procedure will not disturb the disc or stem.

Bray Controls is proud to offer the Bray/McCannalok line of high performance butterfly valves. This product line is recognized as a proven leader with over 30 years of successful service in process industries worldwide. The Bray S40 series unique, patented design received Chemical Processing’s Vaaler Award for Best Product shortly after it was introduced. The simple, innovative design offers rugged reliability and extremely easy maintenance in the field. Independent and internal tests have proven Bray/McCannalok’s superior service life capability, with bubble-tight shutoff through over 100,000 cycles.
The Series 40 valves can be automated inexpensively with Bray’s pneumatic and electric actuators.
When compared to gate, globe, ball, diaphragm and plug valves,the Bray/McCannalok butterfly valve is significantly smaller and lighter weight, therefore installation space, time, and maintenance costs are greatly reduced.
The Bray/McCannalok High Performance Valve delivers the highest quality and highest value available for your requirements.

STEM (B)
The high-strength, one piece stem is 17-4 PH Stainless Steel. The valve stem is standardized for interchangeability of Bray actuators.

DISC (C)
The disc has been engineered to maximize flow and minimize resistance, providing a high Cv. 316 Stainless Steel is standard.

TAPER PINS (D)
Taper pins are precision fit into taper–reamed holes providing a positive connection of maximum strength between the valve disc and stem.

INTERNAL TRAVEL STOP (E)
An internal travel stop has been designed to prevent over travel of the disc, minimizing possible seat damage, therefore extending the service life of the seat.

HANDLE AND NOTCH PLATE (F)
The heavy–duty, spring release handle and 10 position notch plate allow for positioning the valve disc
to precise angle stops between the full open and full closed positions.

BLOW-OUT PROOF STEM (G)
The Series 40 High Performance valve features blow-out proof stem protection. A retaining ring is installed between the machined stem groove and gland retainer step providing full retention of the stem in the unlikely event of internal stem failure.

ADJUSTABLE STEM PACKING
The stem packing system features easy access to adjusting hex head nuts without requiring removal of the actuator. The system consists of a gland ring (H), a gland retainer (I), studs, hex head nuts and lock washers (J). A slight 1/4 turn of the hex head nuts is usually all that is required should field adjustment ever be needed. Both hex head nuts must be evenly adjusted and not overtightened.

STEM SEAL (K)
The stem seal system provides constant compression for a positive seal around the stem. PTFE packing seals the stem, and a carbon fiber anti–extrusion ring contains the packing. Flexible graphite
rings are available for high temperature applications and are standard on fire safe valves. All Class 150 and Class 300 valves have one set of stem seal packing rings and a stem locating plug with a gasket or O-ring seal in the body base. All Class 600 valves have upper and base twin stem seals which balance axial forces on the stem and disc under all operating conditions, and eliminate any
piston effect on the stem.

STEM BEARINGS (L)
Top and bottom bearings, consisting of a 316 Stainless Steel shell with a TFE/glass fabric liner bearing surface, securely support the stem. The stem bearings provide excellent resistance to corrosion and distortion from high temperatures and mechanical loading forces.

SEAT DESIGN


THE HEART OF THE SERIES 40 VALVE
The unique, two-part seat assembly consists of a resilient energizer (M) which is totally encapsulated by the RTFE* seat (N). The assembly is locked in the body recess by a full–faced seat retainer (O). This simple, reliable and proven combination results in many exclusive advantages, including:
• The energizer is completely isolated from all contact with the line media by the RTFE seat.
• Serrations in the seat retainer and body recess secure the seat assembly in place regardless of disc position.
• The full–faced retainer is bolted to the body, locking the seat in the correct position. The seat is secured even without the mating flange.
• The closely confined and well supported seat is energized by the disc and line pressure. The higher the pressure, the tighter the seal. In low pressure and vacuum applications, the energized seat offers superior sealing and longer service life than many other designs.
• Line media is sealed to zero leakage in both directions.
• The seat is self–adjusting for wear and temperature changes.
• Seat replacement is extremely easy –just remove the seat retainer, rotate the disc into the closed position and place a new seat assembly in the machined recess of the body. This simple procedure will not disturb the disc or stem.

For over 30 years the reliability of the Bray/McCannalok has been conclusively proven, both in lab tests and thousands of field applications. After a test of over 100,000 cycles at 720 psi, the seat remained in excellent condition, continuing to provide a bidirectional bubble–tight seal. Even after more than 878,000 cycles at 2 psi, the Series 40 still sealed bubble–tight in both directions.

BRAY/McCANNALOK HIGH PERFORMANCE SERIES 40 VALVES ARE AVAILABLE WITH PROVEN BIDIRECTIONAL FIRE SAFE SEATS ON SIZES 65mm-600mm ANSI CLASS 150 AND 65MM-400MM CLASS 300 WAFER & LUG BODIE

FOR RELIABLE CONTROL OF FLAMMABLE AND HAZARDOUS FLUIDS IN PETROLEUM, PETRO-CHEMICAL, CHEMICAL AND OTHER HIGH-RISK APPLICATIONS, THE FIRE SAFE DESIGN COMBINES SUPERIOR PERFORMANCE, EXTENDED SERVICE LIFE AND COMPLIANCE WITH THE MOST DEMANDING WORLDWIDE FIRE-TEST STANDARDS – BEFORE, DURING AND AFTER A FIRE!
In normal service, the FIRE SAFE combination resilient/metal seat seals bubble–tight in both directions of line media flow through the full rated pressure and temperature ranges. When closed, the disc remains compressed against the resilient mechanically loaded seat, which is securely locked in place by a full–faced retainer. Line media pressure strengthens the seal. In the event of a fire, if excessive heat destroys the resilient seat materials, either partially or completely, the seat provides a constant metal–to–metal backup seal. In real–world fire conditions, line pressure is immediately reduced and the entire area is hosed down. The resulting pressure drop and rapid cool down causes many valves to fail. The FIRE SAFE design does not rely on line media pressure to seal, therefore the valve offers superior low pressure performance than competitive designs. The Inconel® metal seat functions as a spring mechanism, which allows for expansion and contraction without breaking contact with the disc. Additionally, the Inconel seat offers better corrosion and heat resistance and greater strength than the stainless steel seats commonly used. The Bray/McCannalok delivers proven fire safe protection not only in the lab, but also where it counts the most – in the field.
The adjustable stem sealing packing system is composed of flexible graphite and formed graphite rings. These ring materials offer maximum stem sealing capability. The packing can be easily adjusted by a slight turn of the readily accessible hex head nuts.

FIRE SAFE SEAT OPERATION
The seat assembly in normal service contacts the disc with both the resilient seat material and metal seat. During and after a fire, when the resilient material has been partially or completely destroyed, the metal seat provides a positive seal by remaining in constant contact with the disc in either direction of media flow.

FIRE-TEST STANDARDS
API 607 4th Edition Certified. The Bray/McCannalok FIRE SAFE has been thoroughly tested and meets or exceeds the latest international fire test standards. Since its introduction the FIRE SAFE design has passed field applications and lab tests with flying colors, delivering superior performance under the most demanding conditions.

Bray/McCannalok Series 40 valves handle a wide range of conditions and media, such as corrosive chemicals, water, gases, acids, alkalies, hydrocarbons plus many other fluids. Bray’s standard valve line has been specifically designed to meet most applications. When applications demand special requirements, Bray offers valves and materials that meet these needs. Services and optional materials include:

VACUUM
Standard Series 40 valves with TFE seats are recommended for vacuum service down to .02 mm Hg absolute pressure, or 20 microns. For vacuum service down to 1 x 10 -3 mm Hg absolute pressure, or 1 micron, specially prepared valves are recommended. Under certain conditions, these valves serve well in the high vacuum range down to 1 x 10 -6 mm Hg absolute pressure.


STEAM
Series 40 valves are specifically designed for a wide range of high temperature and high pressure applications including onoff and modulating control of hot water, condensed water or chilled water. The Series 40 valve is rated 10.3 bar (150 psi) saturated steam at 185°C for on-off applications. For modulating service, the Series 40 is rated 3.5 bar at 148.8°C. Use of the standard RTFE seat is recommended for this service.

DRY CHLORINE – Gas or Liquid
Special materials as well as assembly and testing procedures are applied to assure bubble–tight closure in these critical services.

SEA WATER
Series 40 valves have been successfully installed in power plants, desalination plants and deep sea drilling projects. Duplex, super duplex and superaustenitic stainless trims can be provided for sea water service. Higher alloy materials are available.

ASH HANDLING AND ABRASIVE
For applications where flow velocity and differential pressure are low, RTFE or UHMWPE seats and electroless nickel plated discs are recommended. For applications requiring improved resistance to wear and particles of higher hardness, a stellite faced disc and FIRE SAFE design are recommended.

CAUSTIC
Valve materials must be selected for sufficient corrosion requirements. Stainless steel is recommended for sodium and potassium hydroxide applications.

HEATING, VENTILATION AND AIR CONDITIONING (HVAC)
Series 40 valves can be used for damping or balancing water flow, main stop valves, block valves, throttling valves, and control of pump suction or discharge.

OXYGEN
Series 40 valves for critical gaseous oxygen service are specially prepared, cleaned, inspected, assembled and tested to ensure removal of all burrs, sharp edges, dirt, hydrocarbon oil or grease, and other contaminants. Each valve is individually wrapped and sealed in polyethylene before shipment.

SOUR GAS
Selected materials of construction meeting NACE standards (MR-01-75) permit ready application and maximum serviceability in these difficult services.

BLOW-OUT PROOF STEM

IN ADDITION TO THE EXCELLENT FEATURES OF THE SERIES 40, THIS HIGH PERFORMANCE BUTTERFLY VALVE OFFERS SUPERIOR ADVANTAGES OVER OTHER VALVES.
When matched against comparably rated plug, globe, gate, ball and diaphragm valves, the reduced
weight and space requirements of the Series 40 is readily apparent. The cost savings of installation and maintenance are substantial. The torque requirements of the High Performance Series 40 Butterfly Valve are also significantly lower. For example, an 200mm Series 40 Class 150 valve weighs 20.5 kg and has a maximum torque of 169 Nm. Comparable plug valves weigh 144 kg with 412 Nm of torque, and ball valves weigh 71 kg with 723 Nm of torque. A gate valve with a comparable rating weighs 140 kg and requires a linear unit for actuation. Therefore, the Series 40 Butterfly Valve requires a much smaller actuator than other valves. Economy, efficiency and proven superior performance establish the Bray/McCannalok as the premier solution for demanding high pressure applications.

DIRECT MOUNTING OF COMPACT, HIGH TORQUE BRAY PNEUMATIC AND ELECTRIC ACTUATORS PROVIDE LOW COST AUTOMATION FOR ON-OFF AND CONTROL SERVICES.
The Series 40 valves can be automated inexpensively with Bray’s pneumatic and electric actuators. These actuators fully complement the Bray/McCannalok and directly mount without the need for large brackets or adapters. Bray has designed the most advanced, highest quality line of actuators and Brayline accessories available today.
