They will automatically shut off the gas supply if fitted with the appropriate motorised valve.

A two port motorised valve supplied to be installed on a 'S' plan system (indirect models only).

Lastly, on systems with zone control, the problem may be caused by a faulty motorised valve which is isolating part of the system.

A motorised valve to switch hot water between the primary circuit and the heating circuit, as demanded by the other controls.

Hot water plate heat exchanger: Stainless multi-plate type with three-way motorised valve on primary supply.

This will mean installing a three-way motorised valve, a cylinder thermostat and making some changes in the pipe layout.

Magnetic flowmeters measure water flow and motorised valves, controlled by the central computer system, direct the flow according to set criteria.

Neway's VFR-1000 motorised valve refacer will do everything that a traditional valve grinder will do, and more.

The output from the Delta to cylinder pump or valve is sent to high limit thermostat to cylinder thermostat and then to motorised valve.

I-Sense Motorised Valve kits have been fitted to Wartsila, Caterpillar and Ruston engines.

This makes the MP2 suitable for 3-port and 2- port motorised valve applications including the ever popular Unishare and Twin Unival system packs.

New controls can include: Motorised valves Allow 2 or more heating or hot water zones to be controlled separately, providing different temperatures and different times to suit requirements.

The pump may have jammed (see below) or failed; the room thermostat may have packed up; or a faulty motorised valve may be preventing water from circulating around the heating system.

The hall-mounted room "stat usually works well in smaller homes, but if you have a larger house then you might consider two or more room "stats, wired to motorised valves, operating individual heating zones.

Moving back towards the motorised valve or pump start adjusting the valves on the return side of the radiators known as the Lock shield Valve to restrict the amount of flow through it.

Stelrad's Ideal compact Extra heat generator, with a maximum output of 8 kW, also provides neater and easier installation, since the pump, programmer and motorised valves are housed within its casing.

If you are installing central heating, you can buy pre-insulated cylinders with various central heating components (such as the pump, motorised valve, thermostat and programmer) already pre-plumbed and pre-wired in place.

The installer is required to wire at least 5 wires correctly to each motorised valve and to the rest of the heating system. This is because the valve act as a relay and the micro or end switch turns on the boiler or pump.

Examples of actuators provided in the Explanatory Notes are clamps which adjust the gap between the electrodes of an arc furnace or motorised valves that control the intake of water or steam in a boiler, furnace or pulping machine.

Balancing is relatively easy, find the point where the heating loop starts, (usually the motorised valve or pump) then select the radiators furthest away, and make sure the Wheel Valve or TRV and the Lock shield valves are fully open.

Note that some types of motorised valve cannot be serviced and have to be replaced (a job that will entail draining down the entire system), but on many newer models it is possible to replace the valve motor and free the valve spindle if it is jammed, without having to interfere with the plumbing.

A differential temperature sensor with a motorized valve can control the bypass function.

Motorized valves for mass flow control in the loops rely on more copper.

Actuators such as motorized valves, light switches and motors.

For larger boilers and when fitting a motorized valve on a gravity hot water circuit, 28 mm or larger should be used.

Injection valve: A motorized valve which links the mixer and sample loop to the column.

The appellant purchased motorized valves, thermostats and transformers used in heating equipment and subsequently sold to various users.

Location of control elements and sequence of operation motorized valves and thermostatic valves piping, fixtures, accessories, and system balancing.

Industrial hot water systems incorporating galvanised steel / copper ring mains and hot water unit heaters including all control equipment i.e. motorized valves, thermostats, programmers etc.

An alternative option is to use an additional room thermostat and 2-port motorized valve for part of the radiator circuit to allow this zone to be heated and controlled at a lower temperature.

Use of the TTS by range safety will close two motorized valves which shut off the flow of liquid oxygen and methane to the engine - thereby terminating engine thrust.
