Do you have an idea of angle valve

Oct 22, 2013

An angle valve is a manually operated valve with its outlet opening oriented at right angles to its inlet opening; used for regulating the flow of a fluid in a pipe.

An angle valve is a fluid regulating device used in plumbing and industry. It has inlet and outlet ports aligned at an angle with respect to each other, the most common angle being 90 degrees. The inlet and outlet ports can be threaded for connecting to galvanized steel and iron pipes, or they can have compression fittings for connecting to copper pipes. When an angle valve is used as a shut-off valve for residential plumbing fixtures, it is called an angle stop valve, or simply an angle stop.

There are many uses for an angle valve in industry and public utilities. A spring-loaded version of a compression angle valve is used for transferring and dispensing compressed fuels, such as liquid propane. Municipal water companies often route pressurized water through an angle valve that is situated to make to accessible. These companies may also install an angle check valve in their lines to prevent the back flow of contaminants into drinking water. An angle valve may also be installed on the outlet at the bottom of a tank storing water or some other fluid so that pipes can be routed vertically from the outlet to another tank or wherever else it is needed.

An angle valve is essentially an enhancement of a basic globe valve (a linear motion valve used to control fluid flow). At ordinary flow rates, pressures and temperatures, angle valves behave similarly to globe valves.

The design of an angle valve means it can be used not only as a control valve, but also as a physical piping elbow. The discharge from an angle valve compares favorably with other types of valves in terms of flow rate and erosion.

The fact that the ends of the valve are at 90 degrees to each other means that its diaphragm, or membrane, can be a simple flat plate. Fluid flowing through the valve must negotiate just a single 90 degree turn and can be discharged downwardly in a controlled, symmetrical fashion.

The globe or angle valve consists of a metal, circular base with a plug and a handle that resembles a wheel or disc. The wheel shifts and initiates the valve plug to open or close. If the valve is opened, liquid can flow through freely, but, when the wheel triggers the plug to close the valve, flow is prevented.

Angle valves are commonly used as shut-off valves for toilets or sinks, and replacing one is a task that requires little skill. The washers within the body of the valve wear away or dry rot with time. Any local home improvement store or plumbing supply store will carry angle shut-off valves. Bringing in your old valve is also the easiest way to find the correct size valve.
