4H230-08S Hand Lever Pneumatic Valve with Spring Return 5-Port / 3-Position Closed Center, 1/4" Port AIRMIXS
The AIRMIXS 4H230-08S is a medium-flow 5-port, 3-position (5/3-way) hand-lever-operated directional pneumatic control valve equipped with a closed-center spool and a self-centering spring return mechanism. Engineered for precise intermediate positioning and inching control of double-acting air cylinders, the valve automatically resets the handle to the neutral center position whenever released. In the center position, all ports are blocked to lock air inside the lines, keeping the cylinder safely in place. Constructed with a high-strength aluminum body, low-friction internal seals, and standard G1/4" main connection ports, it delivers exceptional reliability for machine controls, pneumatic jigs, and automated automation systems
