RS PRO S.84 EN331 Brass Ball Valve - 1/4 Turn T-Handle


RS PRO range of brass manual ball valves. Manual ball valves are used to operate shut off valves which control water flow and pressure. These quarter turn brass full bore ball valves have a T handle and are suitable for high temperature hot water services in industrial applications.

Ball valves can be used for air, gases, water, steam, chemicals, petrochemical products, etc. These valves are simple to use, you move the handle by a quarter of a turn to open or close the valve.

RS PRO have a great range of brass ball valves for the control of flow which can handle various pressures and high temperatures. 2-piece valves can be disassembled making them easier to clean and inspect.

Available in a variety of sizes:
733-5277 - T handle ball valve 1/4 inch F-F
733-5271 - T handle ball valve 3/8 inch F-F

Typical Applications


Manual quarter turn ball valves are available in various sizes to meet a range of applications. They feature a manual hand lever and can be made from brass, stainless steel and plastic. Ball valves are popular as they are reliable and durable and still close securely over long periods making them suitable for shutoff and control applications.

Applications include:
Heating systems
Water treatment
Gas flow control
Liquid flow control

FAQs


How does a manual ball valve work?
A ball valve is a type of shut off valve that controls the flow of liquids or gases by its rotary ball. The valve is open when the ball’s hole is in line with the flow and closed when the ball is rotated by a quarter turn (90 degrees) by the valve handle.

What is the difference between full bore and reduced bore ball valves?
A full-bore ball valve (also known as full port) has an oversized ball so that the hole in the ball is the same size as the pipeline resulting in lover friction loss. In other words, the bore diameter has the same internal diameter as the pipe. A reduced bore valve has a smaller bore diameter than the internal diameter of the pipework it is on.

Warning

Freezing of the fluid in the installation may severely damage the valve
