Valterra Spring Non-Return Valves
The Valterra Spring Non-Return Valves provides a simple means of preventing backflow in pipe work where this would be undesirable i.e. in pumped systems or where Elecro heaters are fitted in line. This Double Union Flapper Non Return Valve (swing check) Valve is probably unique in its design and is the first we have been able to find where the valve can be viewed for periodic cleaning etc. 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 1.5 inch or 2 inch 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.
