Features & Benefits
Sharp Knife-Edge Gate
Precision-ground SS316 knife-edge gate cuts through fibrous media and suspended solids without jamming.
Bidirectional Sealing
Soft elastomer seat provides zero-leakage shutoff in both flow directions.
Compact Wafer Design
Short face-to-face dimension per MSS SP-81 minimises weight and space.
Replaceable Seat and Gate
Both seat and gate can be replaced in-line without removing the valve from the pipeline.
Abrasion-Resistant Liner
Optional polyurethane or rubber liner protects the body from erosive slurry.
Pneumatic Actuator Option
Double-acting or spring-return pneumatic cylinder provides rapid open/close action.
