PVC Double Union Non Return Valves
A Very Reliable Double Union Non Return Valve with minimal resistance which can be easily cleaned by unscrewing the double union fittings.
This Double Union Non-Return Valve 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 Non Return Valve (check) Valve is probably unique in its design and is the first we have been able to find where the valve can be removed for periodic cleaning.
♦ Easy To Dismantle & Maintain
♦ One of the most useful ways of avoiding backflow in pipe work
Truly a superb piece of kit, designed to fit PVC or ABS (Grey or White) 1.5" imperial Pressure Pipe. By using a 1.5" Reducer Sleeve these Non Return Valves can also be use with Solvent Weld Waste Pipe - See 'Related Produts to the left.
