Types of Water Valves - Plumbing Valve Types


Your home's and Industry’s  plumbing system has variety of valves found at various points along the water pipes that allow you to turn off the water during emergencies, or when you need to makes repairs or upgrades. Shutting off the water is often the first step of many plumbing projects. Locating and turning off the appropriate water shut off valve is therefore, very important.




Ball Valve:-

A ball valve is generally a rather massive metal valve sometimes that includes a lever handle. it's designed for fast turn-off, since the valve opens and closes full with a brief 1/4 turn of the lever handle. usually the sort of valve often seen at the most water shut-off for the house & industry.

Gate Valve:-


A gate valve describes the mechanism by that the valve is opened and closed. to show a gate valve on or off, a circular handle is turned to rise or lowers a metal gate within the valve body. once the valve is off the gate blocks the flow of water.


Globe Valve:- 

From the surface, a globe valve resembles a valve, with a rather bulbous metal body. However, in distinction to a valve, a globe valve is intended to allow variable adjustment of water flow. at intervals the valve, there is a baffle with a water flow port running through it The handle operates a plunger with some kind of washer or seal on the bottom; as a result of the handle closes the valve, the plunger moves down against the water-flow port and half closes it off.

Stop-and-Waste Valve:-

A stop and waste valve is also a key irrigation fitting to help keep mechanical device lines free from freeze at intervals the winter. The stop and waste valve is turned on and off with a meter key and once it's at intervals the off position it's going to automatically drain any water at intervals the road.


The water moving through your plumbing got to only travel one way: from the supply lines and out through a fixture, or from a drain to the sewer main. To assure a uni-facial flow at intervals the event of a "cross-connection", a check valve is very important.


Butterfly valves don't seem to be particularly beautiful (it's pretty dis-satisfactory, we know). In fact, they give the impression of being lots like several different valve. The butterfly appellation refers instead to the mechanism within, basically a disc that rotates by handle turns; this after all implies that flow is reduced through the valve.


A diaphragm valve is corresponding to a gate valve during this there is a wheel or knob that moves a element at intervals the valve fitting, that limits the flow of water. in associate passing diaphragm valve, the element is also a diaphragm that settles down over a saddle, thus stopping water flow.


Pressure balanced valves are used to maintain a continuing temperature of water in domestic showers or bathtubs. A diaphragm within the valve permits the operator to line combining of hot and cold water; but within the event of a pressure drop of cold water (for instance, if a bathroom close is flushed), the diaphragm can shift to limit an excessive flow of hot water. several jurisdictions need pressure balanced valves in domestic bathrooms and showers to prevent accidental vituperative.

Solenoid valves are electrically controlled valves which will supply precise on/off control via an automation system. solenoid valves are utilized in buildings wherever an automation system controls the plumbing or HVAC system. Another common use is in irrigation systems wherever a PC controls the watering times or the quantity of water to be applied.
