There are many valves that are used in current plumbing systems, they form an integral part of the system and perform many different tasks. Below is a guide to just a few of these very important fittings and the job they do:
Stop: The stop valve is the best type of valve to fit within a system that will need to utilise a very large amount of water pressure and is the valve that is fitted at the entrance to the home to either start or isolate the flow from the outside mains. It is easily accessed.


Globe: The globe valve contains an internal shaft that has a stopper sat on top, which will move freely in an up and down action to allow water to flow. This valve is normally used when the flow requires regular adjusting. A Radlett Plumber fits and maintains these types of valves.


Thermostatic (radiator): A very popular and regularly fitted valve with plumbers. The TRV as it is known is a great temperature control valve that is fitted to nearly every home’s radiators. This valve provides control of the water flow through the radiators in your home using a thermostat fitted inside. The temperature of the water dictates the action of the valve as set by the homeowner and is a great way of controlling individual rooms according to their use, which can save wasted heat and money. Radlett Plumbers are experienced tradesmen.


Gate: This particular valve is nearly always to be found in systems that have a straight direction of flow. It is also known as a sluice valve. It is operated by means of the raising and lowering of a wedge shaped piece that is fitted to the valve shaft with a wheel to assist in the turning action.
