Understanding What a Bathe Valve Does

A bathe valve is that a part of the bathe which controls the move and mixture of cold and warm water into the remainder of your bathe. It does this utilizing a mix of diverters, move controls and temperature controls.

How does it do it - Diverters, Circulation Controls and Temperature Controls

Temperature Management

All valves normally have a single temperature management. The temperature management varies the proportion on cold and warm water that's combined permitting the temperature of the resultant combine to be managed. As soon as the water has been combined by this a part of the valve varied move controls and/or diverters then direct the combined water to the varied capabilities of the bathe. (By perform we imply any of the bathe shops, e.g. overhead bathe, slider rail, physique jets and so forth).

Circulation Management

A move management is solely a valve managed by a deal with or lever on the valve. It takes water that has already been combined by the valve and restricts its move from full off to full on permitting wonderful management of the speed of move between these two extremes. Every move management typically controls the speed of move from a single valve outlet and from there to a single bathe perform. To manage a bathe with two capabilities comparable to an overhead bathe and a hand-held bathe one possibility is to make use of a bathe with two move controls, every move management independently controls the speed of move to a single outlet, this implies you can have each controls on on the similar time, that is in distinction to diverters (see beneath).


A diverter is a change used to direct water that has already been combined within the valve to one in every of two or extra valve shops. A two-way diverter switches water between one in every of two shops and a three-way diverter switches between one in every of three shops. As well as a diverter has an off place which cuts the availability of water to all of the showers shops. Diverters don't provide water independently to the bathe shops, just one may be on at a time. As well as diverters don't permit wonderful management over the speed of move, though there could also be some management every outlet is principally full on or full off. Observe that in lots of bathe configurations particularly these with an uncovered valve (see beneath) there could also be one other separate diverter on one other a part of the bathe, (normally on the riser which takes the water up the wall) which switches water from the valve between two bathe shops, for instance an overhead bathe and a hand-held one on a slide rail or wall mount.

Sequential Bathe Valve Controls

Most showers have at the least two controls, a temperature management and a number of move management and/or diverters nonetheless a sequential bathe valve has a single lever management combining temperature and move management regulation, As quickly as a sequential management is turned the move to the bathe is turned full on chilly because the deal with is turned to its full extent the move stays on full move however the temperature is elevated to its most. With a sequential valve the temperature con be managed finely however not the move.

Thermostatic and Guide Bathe Valves

Thermostatic bathe valves embrace an inbuilt anti-scald security mechanism which cuts off the move of water if the temperature of the combined water exceeds a (normally) pre-set worth. Guide valves don't present this security characteristic. Some thermostatic valves additionally permit the water temperature to be set and maintained.

On the whole a bathe will likely be equipped water from the identical mains system and boiler as all the remainder of the plumbing in the home, which means that adjustments in water utilization in different components of the home can impact the move of water to the bathe and extra notably could cause a discount within the provide of chilly water to the bathe. This ends in the combined water being delivered by the bathe containing the next proportion of scorching water which means that the water temperature rises. It is in simply such conditions that thermostatic valves defend the usage of the bathe from harm.

Uncovered and Hid Bathe Valves

Typically showers may be classed as uncovered or hid. A hid bathe is one the place a lot of the pipe work related to the bathe is fitted contained in the wall and particularly the bathe valves bathe shops are contained in the wall. An uncovered bathe against this has a bathe valve with shops on the skin of the wall and the pipe work supplying the varied bathe capabilities are seen.

Mixtures of Controls on Bathe Valves

There are 4 commonest mixtures of controls and shops on bathe valves and it is advisable to decide the fitting one for the mixture of bathe options you're having in your bathe. Listed here are the 4 commonest varieties of valves and the way you'll use them:

1. Two Controls and One Outlet: One management is for temperature, the opposite for fee of move it provides one bathe head solely. However particularly on conventional fashion uncovered showers you usually discover a diverter on the inflexible riser a part of the bathe in order that one in every of these valves can be utilized with two bathe heads for instance an overhead bathe and a hand-held bathe on a slide rail.

2. Two Controls and Two Shops: One management is for temperature, the opposite is a diverter which switches between the 2 totally different bathe shops. Nonetheless the diverter doesn't offer you as wonderful management of the speed of move as a move management. You'd use this for 2 bathe shops for instance an overhead and slider rail. However you would possibly desire to make use of the subsequent choices as an alternative.

three. Three Controls and Two Shops One management is for temperature, the opposite two are each move controls independently controlling the speed of move to the 2 totally different bathe shops. You'd use this for 2 bathe shops for instance an overhead and slider rail. It offers you finer management of the speed of move than the 2-control valve with the diverter and you may have each showers on on the similar time which you'll't with the diverter model as a result of that one switches between them.

four. Three Controls and Three Shops One management is for temperature, one is a fee of move management and one is a diverter. Sometimes you would possibly use this for a arrange the place you could have an overhead bathe with one other hand-held bathe that goes on a slider rail and various physique jets (physique jets are normally all equipped by a single outlet from the valve).

You would possibly then have the move management feeding the overhead bathe and the diverter switching between the physique jets and the hand-held. Meaning you possibly can have every of them on individually or you possibly can have the overhead bathe on with hand-held bathe or the overhead bathe on with the physique jets however not the physique jets on with the hand-held. However how you could have this plumbed-in is your selection, you simply have to make it clear to your plumber.

There are different mixtures too together with sequential valves and valves with built-in shops comparable to these which embrace a shower spout or a hand-held bathe and hose. If you would like something uncommon its at all times finest to verify that the parts you get are the fitting mixture to realize what you need and for this you want somebody who's bought the time to speak to you and who is aware of the topic space.
