characteristics

Pressure Relief and Regulating Valves single-stage and two-stage devices are both part of OMA capability list.

The Pressure Relief Valves are often used to protect the hydraulic circuit in case of pump abnormal operation or in case of extreme fluid expansion during operations.

To be compliant with the tight leakage requirement, the valve seat can be made of non-material, already tested and developed in many valves designed by OMA.

The cracking pressure can be set at the required value acting as necessary on the internal spring pre-charge.

Pressure regulating valves, according to the progressive or differential hydraulic commands, deliver a variable pressure to the connected utilities.

The Pressure Regulating Valves are mainly composed of a spool and sleeve coupling. The pressure metering action is achieved by the joint action between spool/sleeve coupling and a pressure limiter valve.
