Motorised Valve

There is control valve that is integral to the operation of any central heating system, this valve is fitted to allow the homeowner to control the heat produced and also where that heat goes, this guarantees they can get more from their system by means of energy efficiency and financial benefits. Sometimes these control valves can malfunction, and if not dealt with straight away will severely interrupt the effectiveness of the system. Ladbroke Grove Plumbers supply and fit new control valves.

New Valve:
The first thing to ensure is that once you know the valve is not functioning make sure that you buy the correct unit. You can do this by taking the old one to your local merchant.
1). At the consumer unit or fuse box remove the fuse or switch off the MCB (mini circuit breaker) for the central heating controls. Drain the system if no local isolators are fitted.
2). Remove the cover from the valve and disconnect its wiring, making a note of the terminals used, to make reconnection easier to do. The valve should be connected to an adjacent electrical junction box. Once you are happy that the valve is isolated, take out the valve by simply cutting through the pipe on each side.
3). In order to fit the new valve, connect the joints to the pipework, then, fit and tighten the valve cap nuts. Connect the valve’s cable to the junction box, then insert the fuse or switch on the MCB. A Ladbroke Grove Plumber can fit all motor driven valves.

New Motor:
Sometimes it is not the fault of the valve, with the motor being defective. You can replace this without having to drain the system.

1). Isolate the electrical supply to the whole system to be sure as motor driven valves can use a permanent live electrical feed. Undo and remove the top cover and loosen the single screw that secures the motor. Open the valve with the manual lever, and remove the motor after cutting the connectors for the two motor cables. 2). Install the new motor, and let the operating lever spring to its closed position. 3). Replace the securing screw, then, strip back and connect the cables tightly, Re-fit the cover, power up and test the valve.”
