The WHS-M-S3-VALVES kit allow for the manifold on your underfloor heating system to easily be isolated from the primary circuit. The kit has been specified to fit the WHS-M-S3-XX manifold range when equipped either with or without the WHS-MS3-MIX mixing unit. With the WHS-M-S3-VALVES isolated, the manifold can be filled, drained, pressure tested etc, without affecting the primary circuit.
Each of the valves is supplied in three pieces for ease of use and versatility. The 1” union screws into the manifold or mixing unit, allowing the red or blue valve handles to be correctly orientated and the optional 22mm adaptor allows the valves to connect to either 1” G Male or 22mm primary supplies.
