Gate Valve


Metal Seated, Swing Check

404 - 150mm

The JOHN cast iron swing check valves are designed to give genuine full-bore flow on lines carrying liquids that are non-injurious to the specified materials. They operate equally well in either horizontal or vertical installations. In service, the valve disc swings away from the seat on a hinge and returns quickly and accurately to the closed position immediately flow ceases or attempts to reverse.
