The double Acting and Spring Return VIP valves (either Normally Open or Normally Closed) are designed with UNI/ISO 7/1 Rp - DIN 2999 (NPT threads on request) gas threaded ends with a combination of control fluid connections in compliance with NAMUR interface. The valves are composed of various sizes from 3/8 to 2. Unidirectional flow and incorporates enhanced fluid dynamics to minimize pressure losses which is depicted in the flow pressure diagram.

The valves are also provided with seals in NBR, FKM or EPDM NBR seals for suitable application air, gas, oils, water, a wide range of fluids, hot water, steam but is unsuitable for application in mineral products (oils, grease, etc..). The valves offers easy mounting in any position (horizontal, vertical or oblique). The external magnet limit switches signals opening and closing of valves.
