Hard-seat pressure control valves regulate system pressure by using a metal-to-metal contact with the internal spring. These control valves perform well in corrosive or extremely high temperature applications.

Soft-seat pressure control valves regulate pressure using a soft material contact on the internal spring in lower pressure hydraulic systems.

Modular pressure control valves regulate pressure on a primary line, while maintaining constant pressure in a secondary line. They feature a check valve to prevent a pressure drop in the circuit.
