Combination flap/gate valves

Combination flap/gate valves are a specific type of end gate valves which - in combination with a flat flap valve -can be both automatically and manually closed in order to prevent liquids from flowing back into the system on which they are mounted. The device’s application is the same as that of a flap valve but it enables users to shut off the outlet in a watertight manner in the event of an emergency or a leak.

They are usually mounted on pipelines of a diameter ranging from 100 to 2000mm.
