Features
Approximately 1 drop (0,07 cc) of fluid will pass from the pilot area to the vented spring chamber every 4000 cycles.
For models with manual load release control option, turn load release clockwise to release load.
Provides hose break protection, prevents loads from drifting and positively locks pressurized loads.
Extremely low leakage. The seat and poppet are heat treated for long life. If the load drifts due to the valve, the seat has probably been damaged by contamination and the valve should be replaced.
Sealed pilot for use in circuits where cross port leakage is undesirable.
Port 4 (vent) should never be blocked as seal weepage will eventually cause valve to malfunction.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
