Glow-worm Ultracom Boiler Diverter Valve (0020132683 / 0020132682)
The Glow-worm Ultracom Diverter Valve Assembly (Part Nos: 0020132683 / 0020132682) is a core hydraulic distribution unit found in Glow-worm’s popular Ultracom high-efficiency condensing boiler series. This complete assembly features a rugged composite polymer body housing the internal cartridge mechanism responsible for alternating the path of primary heated water. When a domestic hot water demand is initiated, the boiler's printed circuit board signals the actuator motor to slide the internal plunger, blocking the central heating loop and routing the high-temperature water straight into the domestic plate heat exchanger.
Complete Hydraulic System Fix: Replacing the full cartridge and housing assembly eliminates recurring faults like internal fluid bypass, sticking valve stems, and housing hairline fractures that simple seal swaps fail to resolve.
Debris and Scale Resistance: Built using advanced engineering plastics that drastically minimize the adhesion of magnetite sludge and limescale, keeping the internal sliding pathways friction-free.
Positive Port Sealing: Features high-grade EPDM rubber seat gaskets engineered to maintain bubble-tight isolation of the radiator circuit, preventing central heating "bleed" during summer tap usage.
Direct OEM Configuration: Manufactured to precise factory specifications to guarantee accurate clip-fit connection alignments with the existing primary pipework and the heat exchanger interface.
