APV RUF check valves are designed for applications where flow return must be avoided.
Check Valves
Check valves are one way valves, in which flow in able to run smoothly one way however if the flow turns, the valve will close to protect the piping.
The APV RUF3 check valve is used at places in production lines where a backflow of product must be prevented. When the pressure is balanced, the valve starts closing by spring force so that it is also closed when the pressure on the spring side rises.
