RS PRO range of stainless steel L and T port ball valves which are used for controlling flow and are an excellent choice for shut-off applications. These ball valves are durable and perform well even after long periods of time.

Ball values 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. Stainless steel ball valves are used due to the materials resistance to corrosion and are often found in aggressive environments.

RS PRO have a great range of 3-piece stainless steel ball valves for the control of flow which can handle various pressures and high temperatures. 3-piece valves can be disassembled making them easier to clean and inspect.

RS PRO stainless steel screwed end ball valves for the control of flow and are available in a variety of sizes and types.
499-1865 - L port ball valve, 1/4-inch BSP F
499-1871 - L port ball valve, 3/8-inch BSP F
499-1887 - L port ball valve, 1/2-inch BSP F
499-1893 - L port ball valve, 3/4-inch BSP F
499-1938 - T port ball valve, 3/8-inch BSP F
499-1944 - T port ball valve, 1/2-inch BSP F
499-1950 - T port ball valve, 3/4-inch BSP F
499-1966 - T port ball valve, 1-inch BSP F

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 values 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

How does a manual ball value 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.
