LE402
Logic Element, Normally Closed, Spool Type, Pilot Valve Adapter 350 bar [5000 psi] · 350 l/min [93 US gpm]
DESCRIPTION AND OPERATION This is a high flow, 2-port logic element where a pilot control valve can be installed into the cavity on the top of the valve. The valve is normally closed from port 1 to 2, with an orifice through the spool connecting port 1 to the inlet port 1 of the control valve. Installing a direct acting relief valve will make this valve a high flow relief valve, a solenoid valve a high flow on/off valve, and a proportional control valve a high flow proportional control valve.
