What's DIN EN check valve ?

  DIN EN check valve is designed to prevent the reversal of flow in a piping system.it's commonly used in piping systems in which globe valves are being used as a flow control valve. They have similar seating arrangements as globe valves.Lift check valves are suitable for installation in horizontal or vertical lines with upward flow.

A   DIN EN check valve is a valve which prevents the suction line from running empty, e. g. after the pump has been stopped. Priming the pump prior to a re-start is therefore no longer necessary.Lift check valves 

Spring-loaded cast steel lift check valves can be installed in the piping in almost any mounting position.Compared with swing check valves, their head losses are higher as the deflection of the flow is much more significant.Lift check valves are preferred when applications require smaller nominal diameters.

Main features of DIN EN check valve

Features and benefits of   DIN EN check valve

  • 1)Quick closing and stable performance:small stroke of valve disc make it possible for a quick closing,a spring loaded disc is even a plus,make the closing quick and reliable.
  • 2)Automatic closing with spring loaded disc. 
  • 3)Very simple construction and easy maitainance.
