The non-return valve is installed on the main line and permits the fluid to flow in only one direction, blocking any back flow.
As usual, it is a "ready to fit" kit and the installation on AP 25 pipes is quick and easy. The valve is already equipped with double clamping brackets.
In order to install this group, all you need is to properly deburr A and D, being sure that the metal edge will not damage the oring during mounting.
Grease the insides of A and D with vaseline and push B and E in, tightening the screws C and G with a torque between 6 and 10 Nm.
Double check that the valve versus matches the flow direction.
