Features & Benefits

The Bray Series 762 bidirectional heavy duty slurry valve is designed for demanding high pressure 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 two-piece bolted flange style. When fully open, the valve is full bore, offering no resistance to line media.

Features

Protective stem cover is standard increasing cycle life in hazardous environments
Unique J-ring steel-reinforced, elastomer sleeve design provides energized, zero leakage shutoff in both directions. Retaining rings included as standard throughout the entire size range
In the open position, the energized sleeves shield all metal components from direct contact with the flowing process media
Robust gate designed for high pressure slurry 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 extended sleeve life
Designed with ample clearance for push-through allowing complete gate closure
Flanged two-piece bolted body allows for easy maintenance and is drilled and tapped to ASME CL150 flange patterns as standard. Other drilling options available upon request
Bottom flush plate with tapped ports offered as an option, allowing for safe discharge of media and easy flush water connection
