Description

3/2 Way Pneumatic Air Pilot Valve – SK320 Series Single Acting


The SK320 Series is a high-quality range of 3/2 way single-acting pneumatic air pilot valves designed for reliable control of pneumatic cylinders, actuators and automation systems. Available in port sizes from 1/8" to 1/2" BSP, the range offers normally closed operation as standard with a normally open option, making it suitable for a wide variety of compressed air control applications.

Unlike electrically operated solenoid valves, the SK320 Series is actuated entirely by pilot air pressure, making it ideal for hazardous environments, remote pneumatic control systems and applications where electrical power is unavailable or undesirable. The compact aluminium construction provides fast response, dependable operation and long service life.
