Hand-Operated Pneumatic Valve with Three Position Lever, Pressure Center: 4H230P-M/S

The 4H230P is a manual pneumatic directional valve with a four-way operation & five ports (P = Pressure, A = Outlet 1, B = Outlet 2, EA = Exhaust for port A, EB = Exhaust for port B). Four-way, three-position, pressure center valves are generally used to stop a double acting cylinder in partial stroke, with pressure on both ends of the cylinder at the center position. This valve is available with either a Detented (-M) or Non-Detented (-S) lever.

Please note that there have been recent design updates to this valve. The specific changes can be found here (see pg. 5): Pneumatic Valve Design Changes. For inventory status of each version, please call us at (650) 856-8833.
