NAMUR valves offer two-way convertibility

Don Horne   

Fesfesto0415to’s new VSNC series of standard solenoid NAMUR valves is two valves in one that suit a wide range of process applications. By simply turning its seal 180°, it converts easily and quickly from a 5/2-way valve into a 3/2-way valve, making it well-suited for use with a single-acting or a double-acting pneumatic actuator. In 3/2-way mode, exhaust air is fed via the seal into the spring chamber of the actuator. This protects the chamber from contaminated ambient air and guarantees a longer service life for the actuator. This new valve series is well-suited for the fermentation of liquids, bulk materials and gases.
