DESCRIPTION AND OPERATION

This is a pilot operated check valve with a separate drain. Free flow takes place from port 3 to 4 and is blocked from port 4 to 3 until pilot pressure is applied to port 1. Port 2 is drained to tank to remove any effect of pressure in port 3 affecting the pilot pressure required to keep the valve open.
