Product Overview
Robust slurry valve with elastomer seat for durability and easy maintenance
Reliable Solution for Handling Abrasive Industrial Media
The Bray Series 765 bidirectional knife gate valve is specifically designed for demanding slurry applications. The dual elastomer seat and push-pull gate design facilitate self-cleaning, preventing media buildup. The rugged ductile iron body features a compact wafer design. When fully open, the valve provides full port opening with no obstruction to pipeline media.

Features and Benefits
A - Bonnet
Design supports simple and quick conversion between manual and pneumatic operation. Features 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 emission from the top of the valve.
C - Elastomeric Sleeve
Metal-reinforced elastomeric sleeve provides energized bidirectional zero-leakage sealing.
D - Energized Sleeve
In the open position, the energized sleeve protects all metal parts from direct contact with flowing process media.
E - Rugged Gate
Available in a variety of corrosion-resistant alloys for the rugged gate, selectable based on application requirements.
F - Unrestricted Flow Path
Unrestricted flow path achieved through full-port valve design, minimizing pressure drop and extending valve life.
G - Gate Fully Closed
Ample push-through clearance supports full gate closure.
H - Compact Wafer Body
Compact wafer body is easy to install and drilled to ASME CL 150 flange standards. Other drilling options available upon request.
I - Flush Plate with Threaded Wash Port (Optional)
Optional flush plate with threaded wash port for safe media discharge and easy wash water connection.
