Swing check pneumatic valve installation direction

Swing check pneumatic valve commonly used in liquid pipeline more, if it is a vertical pipe, gas or with aerodynamic lift check valve.
if it is vertically from top to bottom, with disc check pneumatic valve, this valve on seen. Swing check vertical pipe pneumatic valve can only be from down to up, down from the became a decoration.









actually swing check the level of the pneumatic valve installation is absolutely right.
as to whether can vertical installation, most that is possible.
according to the principle of swing, if the flow is from down to up, so it can play a role completely, even if the back pressure is very low and can guarantee the effect of non-return. Flow from bottom to top, but if its under no pressure condition, its internal swing plate due to the effect of gravity is on, so when the back pressure is low, especially in gas medium, it is easy to through one-way pneumatic valve pour into medium. That is to say, swing check pneumatic valve should be installed vertically is conditional.
