The Check Valve is of fundamental importance in protecting hydraulic installations, as it prevents water from returning when the pumps are stopped and, in addition, it also maintains the water column during the time in which the pump is not working.

Therefore, their use is essential. But do you know how check valves are installed?

We've prepared a step-by-step guide to help you.

1 – Check the pump inlet. If the diameter is the same, great. If not, use an adapter.

2 – Observe the flow direction indicated on the body of the piece.

3 – Before assembling, clean all piping to eliminate all debris.

4 – Remove the end protections.

5 – During installation, the Valve must be closed so that dirt or splashes do not fall during welding, as they could compromise the seal.

6 – Valve and piping must be perfectly aligned. This will prevent damage during handling.

7 – To open the valve, turn it counterclockwise. To close it, turn it clockwise.

Benefits

– It is capable of performing its functions without the need for human force.

– Some valves have bypass valves, which allow the backflow of trapped water when the pump is stopped. This allows the pipes to be emptied so that parts can be removed for repair or replacement.

– Its opening and closing are faster than that of the gate valve .
