Description
5/2 & 5/3 Way Pneumatic Air Pilot Valve – SK520 & SK530 Series
The SK520 & SK530 Series is a high-quality range of 5/2 and 5/3 way pneumatic air pilot valves designed for reliable control of single and double-acting pneumatic cylinders, actuators and automation systems. Available in 1/8", 1/4", 3/8" and 1/2" BSP port sizes, the range provides dependable external air pilot operation for industrial process control, factory automation and compressed air installations.
Unlike electrically operated directional valves, the SK520 & SK530 Series is actuated entirely by pilot air pressure, making it ideal for hazardous environments, remote pneumatic control and applications where electrical operation is not required. The robust aluminium construction, compact design and multiple valve configurations provide flexible, long-life performance for demanding industrial applications.
