Features
Wet-armature solenoid with coil immersed in oil, low wear, long service life, impact resistant, stable shifting. H-function center position with all four ports connected allows the cylinder to float freely and system pressure relief at center. Built-in manual override allows manual testing of shifting when power is off. Standard ISO subplate mounting, highly versatile, direct replacement for same-spec domestic valves. Nitrile seals suitable for ordinary mineral hydraulic oil; supports long-term continuous operation, suitable for machine tools and presses.
