EG11W Female Screw diaphragm valve is a type of diaphragm valve with British standard that is only operated by applying torque on the handwheel. EG11W Female Screw diaphragm valve operates when the diaphragm valve operator applies a torque on the handwheel to either start or stop fluid flow. The start of fluid flow through a manual diaphragm valve starts when the handwheel is rotated in the clockwise direction forcing the stem and compressor to move upwards. This then forces the diaphragm to move upwards and this leaves the diaphragm valve open for fluid to flow. To stop EG11W Female Screw diaphragm valve, the handwheel is then rotated in the anticlockwise direction forcing the diaphragm to create a tight seal with the body and thus blocking any fluid flow. 

Applications of EG11W Female Screw diaphragm valve includes foods and beverages, chemical processing, paper and pulp, pharmaceuticals, and water supply among others. Advantages of EG11W Female Screw diaphragm valve are simple and compact design, cheaper, easy to clean and repair, versatile, free from leakage, and bi-directional fluid flow.
