Product Applications

Zoom in on interactive diagrams.

Choose a Category

Pneumatically Operated Piston Balanced High Volume

Features an angled body and inverted trim, and provides extended production time through flowback and in erosive applications.

Pneumatically Operated Piston Balanced Throttling

Best pneumatic option for erosive service because the trim moves up out of the flow path.

Pneumatically Operated Diaphragm Balanced

Balances upstream and downstream pressures to eliminate imbalance of opening/closing forces due to pressure differential.

Lever Operated Piston Balanced Throttling

In this zero-emission valve, the upstream and downstream pressures balance the forces on the trim, separated by a piston.

Lever Operated Piston Balanced

This zero-emission valve is the best lever operated option for erosive service because the trim moves up out of the flow path.

Lever Operated Diaphragm Balanced

This zero-emission valve uses upstream and downstream pressures to balance the forces on the trim, which are separated by a diaphragm.
