Features and benefits

Knife gate valve for demanding applications – BRAY 762

The Bray 762 Series Heavy Duty Bi-Directional Grout Valve is designed for demanding high pressure mud applications. The double elastomeric seats and the design of the pass-through gate facilitate self-cleaning and avoid accumulation of media .

The durable ductile iron body is offered in a two-piece bolt-on flange style. When fully open, the valve allows unrestricted flow and offers no resistance to line media.

ADVANTAGES

 

  • The protective cover on the stem is standard, which prolongs the duration cycle in hazardous environments .
  • The unique J-ring steel reinforced elastomeric sleeve design provides a energized seal in both directions. Retaining rings are included as a standard feature on all size ranges.
  • In the open position, the energized sleeves protect all metal components from direct contact with the flow processing media.
  • Solid gate designed for high pressure mud applications and available in a wide range of corrosion resistant alloys.
  • Unrestricted flow path with minimal pressure drop achieved through full port valve design for long cuff life.
  • Its design with a wide passage space allows closing the damper completely .
  • Two-piece bolted and flanged body allows easy maintenance , and is drilled and tapped in accordance with ASME CL150 flange patterns as standard. Other drilling options are available upon request.
  • Bottom discharge plate with threaded ports as an option, allowing safe discharge of the media and easy connection of the purge water.
