The AIRMIXS 4H330-10S is a heavy-duty, high-flow 5-port, 3-position (5/3-way) hand-lever-operated directional pneumatic control valve featuring a closed-center spool and a self-centering spring return mechanism. Designed for intermediate positioning, inching control, and mid-stroke holding of larger double-acting pneumatic cylinders, the spring-loaded handle automatically returns to the neutral center position as soon as it is released. In the center position, all ports are blocked to trap air pressure inside the lines and hold the cylinder safely in place. Built with a rugged anodized aluminum body, low-friction internal seals, and G3/8" main connection ports, it ensures smooth manual operation and dependable performance in industrial machinery, clamping systems, and automated production setups.
