Stop Diaphragm Valve
Item Name Code (INC) 13619
 |
A valve designed specifically so the diaphragm seals the flow stream from the valve operating mechanism. The flow is controlled by the lifting of the diaphragm from or compressing it against an integral seat. For packless diaphragm valves which utilize a diaphragm as packing and a disk to control the flow, see VALVE, Y.
Additional Information for Stop Diaphragm Valve
A stop diaphragm valve is a type of valve that is used to control the flow of fluid in a pipeline. It consists of a diaphragm, which is a flexible membrane that separates the valve body into two chambers. When the valve is in the closed position, the diaphragm seals off the flow path, preventing any fluid from passing through. When the valve is in the open position, the diaphragm is lifted or pushed aside, allowing fluid to flow through the valve.
Stop diaphragm valves are commonly used in applications where precise control of flow is required, such as in water treatment plants, chemical processing plants, and pharmaceutical industries. They are known for their reliable sealing capabilities, as the diaphragm provides a tight seal against the valve body, preventing any leakage.
These valves are typically operated manually, using a handwheel or lever, but they can also be automated using pneumatic or electric actuators for remote control. The diaphragm material can vary depending on the application and the type of fluid being handled, with options such as rubber, PTFE, or metal.
Overall, stop diaphragm valves are a versatile and reliable option for controlling fluid flow in various industries, offering precise control, tight sealing, and ease of operation.
