Pressure compensator cartridges - CP700-2

This is a 3-ported, normally closed, vent to open spool type logic element. Port 1 is connected to port 3 through an orifice. By opening port 3 to tank,flow can pass from port 1 to port 2 but not from port 2 to port 1. Closing port 3 will prevent the valve from opening from port 1 to port 2. By controlling the flow or pressure out of port 3 with a secondary valve, the valve can be used as an on/off valve or in a pressure control function
