Festo 18 mm solenoid valve for pneumatic control

The Festo VSVA-B-P53C-ZH-A2-5C1 is a 5/3 closed-centre piston gate valve designed for compressed-air systems that need reversible flow and mid-position blocking. It operates on 12 V DC with a 1.8 W coil and provides a standard nominal flow rate of 450 l/min. An integrated LED shows signal status while a non-detenting manual override allows quick local actuation.

Pilot-operated design with external pilot supply

This valve uses external pilot air at 3 to 10 bar so the main operating pressure can range from -0.9 bar to 10 bar without affecting pilot reliability. The 18 mm width suits manifold assemblies where space is limited and the mounting position is unrestricted. Flow control options on the exhaust ports let installers tune cylinder speed without extra components. Soft sealing and overlap lap minimise internal leakage across the pressure range.

100 % duty cycle for continuous cycling

With an on switching time of 18 ms, off time of 30 ms and a changeover time of 20 ms, the valve repeats reliably in high-frequency sequences. The 100 % duty cycle rating means the coil can stay energised indefinitely without thermal derating. Permissible voltage fluctuation of -15 % to +10 % accommodates typical industrial supply variation. Vibration and shock resistance to FN 942017-4 and EN 60068-2-6 severity level 2 suits transport and machine-mounted installations.
