What's cast steel lift check valve?

Cast Steel Lift 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.

They are recommended for use with steam, air, gas, water, and on vapor lines with high flow velocities.the lift check valves are normally designed with spring,it's closed by default, requiring more pressure to open their door and allow fluid through.

A Cast steel lift 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 cast steel lift check valve

Features and benefits of Cast Steel Lift 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.
  • 4)Similar design as the globe valve,could be used as control valve by modifying the disc structure.
