|3/4/5 Port Solenoid Valves
-
Why does my 5-port solenoid valve malfunction when operated at a low pressure (0.1 MPa)?
-
Internal pilot operated solenoid valves use pilot pressure to switch the valve body and change (control) the flow passage. If the pilot pressure does not reach the min.
operating pressure for valve body switching (varies between 0.1 to 0.2 MPa depending on the model), switching failure may occur. To use a 5-port solenoid valve at a low pressure, you can replace it with an external pilot type valve or a direct operated type valve.
Internal pilot type valves
With the solenoid’s electromagnetic force, a small pilot operated valve (direct operated 3-port valve) is switched, and the supply pressure is sent to the main valve, which switches the main valve.
