RS PRO Stainless Steel Reduced Bore, 2 Way, Ball Valve, BSPP 3/4in, 68bar Operating Pressure

RS PRO General Purpose Manual Ball Valve. Introducing the RS PRO general purpose manual ball valve designed for industrial applications. Manual ball valves are used to operate shut off valves which control water flow and pressure. 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. Stainless steel ball valves are used due to the materials resistance to corrosion and often found in aggressive environments. RS PRO have a great range of reduced-bore quarter-turn stainless steel ball valves for the control of flow which can handle various pressures and high temperatures. Available in a variety of sizes:. ; 499-2789 499-2789 - 1/4 inch BSPP F-F ; 499-2795 499-2795 - 1/2 inch BSPP F-F ; 499-2802 499-2802 - 3/4 inch BSPP F-F ; 499-2818 499-2818 - 1 inch BSPP F-F ; 499-2824 499-2824 - 1-1/4 inch BSPP F-F ; 499-2830 499-2830 - 1-1/2 inch BSPP F-F ; 499-2846 499-2846 - 2 inch BSPP 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 value 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.
