RFS Air valve 1.5 inch model 2W40040

Air valve Features:

  • The Air valve allows excess air to escape while keeping pipeline fluids contained within the pipeline during operation.
  • Also, allows air to escape from the pipes while they are being filled.
  • With direct acting (zero rated) the valve can operate at pressures as low as 0 bar since the solenoid directly activates them and there is no need for a pressure differential between the intake and exhaust ports.
  • A diaphragm structure transmits force to open, close, or control a valve, It is a pressure-responsive, flexible element.
  • Expansion valves are used to control the flow of cooling liquid between a refrigeration system’s high side and low side.
  • Has an encapsulated coil ideal for continuous service and consistent operation.


Air valve Description:

In comparison to designs created by competitors in the market, this solenoid valve has an edge in long-term corrosion resistance and extended operating lifetime because of the use of quality-tested brass materials combined with stainless steel alloys. it can also tolerate high temperatures and pressures while still operating at its best performance. It is widely utilized in a variety of mechanical engineering projects.
