Description
1/4" Pneumatic Air Pilot Valve – SB520 & SB530 Series 5/2 & 5/3 Way
The SB520 & SB530 Series is a compact range of pneumatic air pilot directional control valves designed for fast, reliable operation of pneumatic cylinders and automation systems. Available in 5/2 and 5/3 configurations, the range offers single or double pilot operation together with exhaust centre or pressure centre options for flexible pneumatic control.
Unlike electrically operated solenoid valves, the SB Series is actuated entirely by pilot air pressure, making it ideal for hazardous environments, remote pneumatic control systems and applications where electrical operation is not required. The mounting dimensions are compatible with equivalent SMC pneumatic pilot valves for straightforward replacement or system integration.
