5/3 Air Pilot Pneumatic Valves

5/3 external pilot pneumatic valves for applications where pilot pressure is supplied independently of the main air supply. Available with closed centre, pressure centre and exhaust centre spool configurations, aluminium body construction, double air pilot operation and BSP port sizes from 1/8" to 1/2". Ideal for low-pressure systems, vacuum applications, process automation, machine building and pneumatic control systems requiring reliable directional control with an external pilot supply. Our 5/3 external pilot pneumatic valves provide dependable directional control where the pilot air supply is independent of the main system pressure. External pilot operation allows reliable valve shifting in applications with low or fluctuating line pressure, vacuum systems and specialised pneumatic control circuits. Available with closed centre, pressure centre and exhaust centre spool configurations, the range includes aluminium body construction, double air pilot operation, 1/8", 1/4", 3/8" and 1/2" BSP ports, and operating pressures up to 8 Bar, making these valves ideal for industrial automation, machinery, OEM equipment and process control applications.
