Bray Valves

BRAY / McCANNALOK

Offering superior advantages over other valves.

The cost savings of installation and maintenance are substantial. Economy, efficiency and proven superior performance establish the Bray/McCannalok as the premier solution for demanding high pressure applications.

  • Torque requirements of the High Performance Bray/McCannalok butterfly valves are significantly lower.
  • Bray/McCannalok valves require a much smaller actuator than other valves.

When matched against comparably rated plug, globe, gate, ball and diaphragm valves, the reduced weight and space requirements of the Bray/McCannalok is apparent.

High Performance Valves

Bray/McCannalok valves can be automated inexpensively with Bray’s pneumatic and electric actuators. These actuators directly mount without the need for large brackets or adapters. Bray has designed the most advanced, highest quality line of actuators and accessories available today.

Bray compact, high torque pneumatic and electric actuators provide low cost automation for on-off and control services.
For over 30 years the reliability of the Bray/McCannalok has been conclusively proven, both in lab tests and thousands of field applications."

SEAT DESIGN:

THE HEART OF THE BRAY/McCANNALOK VALVE

The unique, two-part seat assembly consists of a resilient energizer which is totally encapsulated by the seat. The assembly is locked in the body recess by a full-faced seat retainer. 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 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.

Fire Test Standards API 607 5th Edition Certified

APPLICATIONS

  • SEA WATER: Bray/McCannalok valves have been successfully installed in power plants, desalination plants and offshore drilling projects. Duplex, super duplex and super austenitic stainless trims can be provided for sea water service. Higher alloy materials are available.
  • HEATING, VENTILATION AND AIR CONDITIONING (HVAC): Bray/McCannalok 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: Bray/McCannalok 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.
  • VACUUM: Standard Bray/McCannalok valves with RTFE 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: Bray/McCannalok valves are specifically designed for a wide range of high temperature and high pressure applications including on-off and modulating control of hot water, condensed water or chilled water. The Bray/McCannalok valve is rated 150 psi (10.3 bar) saturated steam at 366°F (185°C) for on-off applications. For modulating service, the Series 40 is rated 50 psi (3.4 bar) at 300°F (149°C). Use of the standard RTFE seat is recommended for this service.
  • CAUSTIC: Valve materials must be selected for sufficient corrosion requirements. Stainless steel is recommended for sodium and potassium hydroxide applications.
  • DRY CHLORINE (GAS OR LIQUID): Special materials as well as assembly and testing procedures are applied to assure zero leakage closure in these critical services.
  • SOUR GAS: Selected materials of construction meeting NACE standards permit ready application and maximum serviceability in these difficult services.
