What is the opening pressure of a DN100 swing check valve?

Thread Content

A DN100, PTFE-lined swing check valve is installed on the vertical pipe at the outlet of a pump. The pump has a head of 30 m and a flow rate of 2 m3/h; the fluid contains trace amounts of solids. Is there any requirement regarding the opening pressure for this valve when it is opened? Can it be opened?

This swing check valve has a very low opening pressure; if no spring is installed, it can be opened with just a slight amount of pressure
