Non Return Valve

  • Opening pressure 0.5 bar
  • Gasket option : EPDM /Silicone/Viton

Non Return Valve is designed to control the fluid flowing in only one direction, preventing process flow from reversing. Fluid flow in the desired direction opens the valve in term flow pressure against spring loaded, while backflow forces the valve closed in term spring.

Working Principles

1. NRV opens when the pressure below the valve seat exceeds the pressure above the valve seat. The valve close when pressure equalization has been achieved. A higher counter pressure will allow the valve to close. This type is spring loaded.
