AVC Globe Valve
AVC Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service. Globe valves consist of the following moving parts - the disk, the valve stem, and the handwheel. The stem connects the handwheel and the disk. It is threaded and fits into the threads in the valve bonnet. The location of the valve disk in relation to the valve seat allows or restricts flow. The direction of fluid flow through the valve changes several times, which increases the pressure drop across the valve. In most cases, globe valves are installed with the stem vertical and the higher-pressure fluid stream connected to the pipe side above the disk, which helps to maintain a tight seal when the valve is fully closed. When globe valves are open, the fluid flows through the space between the edge of the disk and the seat. These valves are commonly used as a fully open or fully closed on/off valves, but they may be used for throttling as long as fine adjustments are not required. Globe valves provide the following advantages: they offer precise throttling and control and have high-pressure limits. Conversely, they offer a low coefficient of flow and are not good selections in applications that require cleanliness or sterility. AVC Valve specializes in the design and production of a wide range of globe valves, such as Cast iron globe valve,Ductile iron globe valve,Cast steel globe valve,Stainless steel globe valve,Forged steel globe valve,Cryogenic globe valve and Bellow seal globe valve etc. All of AVC Valves' globe valves are designed,manufactured and tested to API,ASME,ANSI,JJS,DIN and BS standards. |
