Features & Benefits

The Bray Series 746HP features a one-piece polyurethane molded liner throughout the body and chest providing Zero Leakage shutoff in the most abrasive applications. The liner extends over the front face of the body, ensuring total protection from abrasive media and eliminating the need for additional gaskets.

 

The one-piece, durable ductile iron body is offered in a compact wafer style for ease of handling and installation.

  • A. Stem Protection

    Upper and lower protective stem cover is standard in all models, increasing cycle life in hazardous environments.

  • B. Durable & Field Replaceable Packing

    Multi-layer square packing with energized quad seal provides exceptional gland sealing.

  • C. Superior Polyurethane Liner

    Standard one-piece ductile iron body with polyurethane molded liner throughout. Polyurethane body liner is rated up to 194°F/90°C and completely protects valve body from abrasive line media.

  • D. Unrestricted Flow Path

    Unrestricted flow path with minimal pressure drop achieved through full port valve design for extended valve life.

  • E. Optional Gate Materials

    Available in a wide range of corrosion-resistant alloys, the robust tapered edge gate efficiently cuts through thick slurries or solids in the flow.

  • F. Flush Seat & Non-Purging Design

    Seat and port designed to be flush eliminating cavities where media can collect and prevent full gate closure.
