I would like to ask what type of check valve is suitable for installing in nitrogen pipelines
Thread Content
I’m new to this and need to install piping for nitrogen lines; I don’t know what type of check valve would be suitable. Could someone please give me some advice? Thank you.
A regular one will do, but pay attention to the spring. Gravity-based options are also acceptable, but you need to consider the installation position – whether it should be horizontal or vertical. For specific details, consult the manufacturer
The nitrogen check valve in our area is spring-type, with a nitrogen pressure of 0.6 MPa. Hope this helps you
It mainly depends on whether the pipeline you are installing is horizontal or vertical to select the appropriate check valve.
It’s a heavy-lift, lift-type design, that is, a spring-type design, installed horizontally; this is suitable for small-diameter pipes in general. If the pipe diameter is large, a swing-type valve can also be used; its shaft is installed horizontally, and the valve core remains in a sealed position at all times in its natural state.
