What is a swing check valve?
A swing check valve is mounted with a disc that swings on a hinge
or shaft. The disc swings off the seat to allow forward flow and
when the flow is stopped, the disc swings back onto the seat to
block reverse flow. The weight of the disc and the return flow has
an impact on the shut-off characteristics of the valve.
Advantages of VERVO swing check valves
VERVO swing check valves are designed with focus on easy access to
maintenance. By unscrewing a few bolts the bonnet assembly
including hinge and disc can be removed from the body, and
maintenance can be performed.
