Description

A check valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction and so designed to prevent any flow reversal of fluids. An arrow marked on the body shows which way it most be installed. Vertical mounting is advised on an upward flow. In case of an horizontal mounting, the pressure difference between downstream and upstream to ensure sealing should be at least 1bar.
