Pneumatically Operated Piston Balanced

Allows for higher pressure differential than the Diaphragm-Balanced Version.

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

Lever Operated Piston Balanced

Upstream and downstream pressures balance the forces on the trim, separated by a piston.

Lever Operated Diaphragm Balanced

Upstream and downstream pressures balance the forces on the trim, separated by a diaphragm.
