The Bray Series 765 bidirectional knife gate valve is designed for demanding slurry applications. Twin elastomer seats and push-through gate design facilitate self-cleaning and prevent media build up.
The durable ductile iron body is offered in a compact wafer style. When fully open, the valve is full bore, offering no resistance to line media.

Features & Benefits
-
A - Topworks
Designed for easy, quick conversion between manual and pneumatic actuation. Featuring a lubricant injection port for continuous, smooth operation with minimal maintenance.*
-
B - Secondary Wiper Seal
Self-adjusting secondary wiper seal extends gate life and prevents discharge from top of valve.
-
C - Elastomer Sleeve
Metal-reinforced, elastomer sleeves provide energized, zero leakage shutoff in both directions.
-
D - Energized Sleeve
In the open position, the energized sleeves shield all metal components from direct contact with the flowing process media.
-
E - Robust Gate
Robust gate available in a wide range of corrosion resistant alloys to suit the application.
-
F - Unrestricted Flow Path
Unrestricted flow path with minimal pressure drop achieved through full port valve design for extended sleeve life.
-
G - Complete Gate Closure
Ample clearance for push-through allows complete gate closure.
-
H - Compact Wafer Body
Compact wafer body allows for easy installation and is drilled and tapped to ASME CL150 flange patterns as standard. Other drilling options available upon request.
-
I - Drain Plate with Purge Ports (Optional)
Drain plate with tapped purge ports offered as an option, allowing for safe discharge of media and easy flush water connection.
