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


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.
