Double Union Non Return Flapper Valve

This Double Union Non Return Flapper Valve has minimum resistance with the advantage that waste particles can be removed by unscrewing the double union fittings.

This valve provides a simple means of preventing backflow in pipework where this would be undesirable, for example in pumped systems or where in-line equipment is fitted.

The Flapper type non return valves create no back pressure on the pumps and the swing check just swings out the way.

Truly a superb piece of kit, it will fit any 1 inch, 1.5 inch, 2 inch and 3 inch imperial pressure pipe and is solvent weld also. Reducing sleeves can also be glued in the socket unions to use these flapper valves with normal Black Solvent Waste Pipe.
