low noise type Torque pilot operated Solenoid Controlled Relief Valve is a combination of a low noise type pilot operated relief valve and a Torque solenoid operated directional valve. Hydraulic parts is used for no-load pump operation by using electric signals or work with a remote control relief valve, for two or three pressure control of the hydraulic system. Special designs for hydraulic circuiting system which is able to provide low noise and quick response. low noise type pilot operated Torque Solenoid Controlled Relief Valve brings the features of meeting strictly pressure & noise level standards, which is mainly customers requirement. Piping between the two valves is eliminated as the solenoid valve is directly mounted on the relief valve and connected with the relief valve vent. Pump pressure may be unloaded remotely by an electrical signal to the solenoid, or by connecting the pilot relief valve to the solenoid valve ports.
