DSS Valves

A Knife Gate That Can Actually Cut
A Key Design Feature Behind DSS Valves

As odd as it sounds, traditional knife gate valves cannot cut through material on a repeatable basis. Solids in the pipeline cause traditional gates to deflect, warp and leak to atmosphere.

 

Our Guided Shear Gate design consists of two key elements: a shearing tip and internal gate guides. From open to close the gate is guided the entire way removing any option to deflect when solids are encountered. When the material is struck by the shearing tip it is fractured and angled away, enabling zero leakage where the gate meets the primary seal. A secondary seal further eliminates any possible leakage to atmosphere.
