Festo namur valve VSNC

The Festo namur valve VSNC is used for distributed control systems, with the pilot valve able to be adapted for use with either a single-acting or a double-acting actuator for greater flexibility. Turning the seal around 180° converts a 5/2-way valve into a 3/2-way valve. In the case of the 3/2-way function, exhaust air is fed via the seal into the spring chamber of the actuator. This protects the spring chamber from contaminated ambient air and ensures a longer service life for the pneumatic actuator.

Available in a wide range of AC and DC coil voltages, the valve has a rebreather function to help prevent internal actuator corrosion. In addition to the standard coil range, an IEC-EX certified solenoid system provides protection against potentially explosive environments. The design of the valve means that any of the coils, even with different types of protection, can be mounted on a stainless steel armature tube, allowing versatile applications.
