SKU: 4V310B

4-Way, 5-Port, 2-Position Directional, NAMUR Actuator-Mount Pneumatic Solenoid Valves


The 4V310B is a pneumatic directional solenoid valve with a four-way operation & five ports (P = Pressure, A = Outlet, EA = Exhaust for port A). Four-way, two-position valves are generally used to fully extend a double acting (air return) cylinder, or in applications with similar operation. NAMUR-style valves are designed to mount onto standard pneumatic actuators to control the operation of air-actuated valves (ball valves, etc.)
