Polished chrome plated square designer straight manual radiator valve set containing 1 x manual on/off radiator valve and 1 x lockshield valve.
Every radiator or heated towel rail needs 1 x Manual On/Off Radiator Valve & 1 x Lockshield to be installed on a central heating system. Geyser list both items together, so you only need to buy 1 of these sets per radiator or towel rail.
These radiator valves have modern styling to suit contemporary and classic radiator and towel rail designs. Although quite neutral is design, their square/cube shaping is especially suited to radiators and towel rails with vertical or horizontal square or rectangular profiles. Compact and neat, they allow the designer radiator or heated towel rail to be the star attraction whilst still being quality manufactured and fulfilling the practical needs of radiator valves.
Manual Control
This manual valve set is NOT thermostatic (or a TRV set as they are most commonly known). TRV is plumber's shorthand for 'thermostatic radiator valve'. Rather than a thermostatic TRV which has graduated temperature settings, the manual control valve in this set is simply on or off. The valve can be partly closed off to provide crude temperature control by restricting the hot water to the radiator or towel rail, but there is no thermostatic capsule inside to sense temperature. The larger control valve with the hand wheel is recommended to be fitted on the flow side (where the water flows into the radiator) and the lockshield is fitted on the return side (where the water flows out of the radiator).
Manual radiator valve sets are most commonly used on small to medium sized radiators and most sizes of heated towel rails where thermostatic temperature control may not be essential. Usually, but not always, manual radiator valve sets are less expensive than thermostatic valve sets.
Which Valves Do I Need?
These are straight valves and are most commonly used on on heated towel rails with underside connections (almost all heated towel rails) when your pipes come out of your floor. They are also used on radiators where the radiator connections are on the underside of the radiator (quite rare on designer radiators) and your pipes come out of the floor. However, we recommend you visit our choosing radiator valves page for a full explanation of the different orientations of valves available and how they combine with different pipework configurations.
If you still don't feel confident enough to buy the valves you need or the pipework set up has not been decided yet, then just purchase the radiator and buy the radiator valves later. Alternatively speak to your heating engineer who may already know exactly which valves you need. There are three possibilities - right angled valves, straight valves and corner flat front valves. Even if you choose the wrong valves, we will refund you in full for valves returned in brand new condition, so don't worry if you make a mistake.
Different Pipework Sizes
This radiator valve set connects to the UK standard 15mm diameter pipework. However they are super easy to adapt to fit on to microbore 10mm and 8mm pipework by means of an additional, inexpensive brass pipework 10mm or 8mm reducer fitting. The reducer is brass in colour but is out of sight because it sits inside the connecting nut of the valve and cannot be seen once installed.
Quality
Radiator valves can vary wildly in price but can look very similar. The price differences are down to the quality of the brand and the amount of brass (weight) used in the manufacture of the valves. Brass is the raw material used in the manufacture of radiator valves. All Geyser radiator valves are of equivalent quality as well-known brands such as Drayton, Danfoss and Honeywell and are always manufactured with a high, heavyweight brass content. The weight matters because even the highest quality radiator will look much less stylish with lightweight, cheap radiator valves connected to it. Certainly, these radiator valves cannot be compared to Screwfix or B&Q valves.
Other
In order to get better performance out of your heating system, ask your heating engineer about balancing your central heating system. It is an easy procedure, but your radiator valves play an important part in the process. After balancing your system, the result is even heat distribution across all your radiators and towel rails in your home.
