China diaphragm valve manufacturer, factory and supplier. Diaphragm valve is a type of valve that is only operated by handwheel, pneumatic actuator or electric actuator. Diaphragm valve manufacturer produce various types of these diaphragm valves which include straight-through diaphragm valves, weir type diaphragm valves, plastic diaphragm valves, sanitary diaphragm valves, and hygienic diaphragm valves among others.

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 G41J-10 Rubber lined 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 diaphragm valve include foods and beverages, chemical processing, paper and pulp, pharmaceuticals, and water supply among others. Advantages of diaphragm valve are simple and compact design, cheaper, easy to clean and repair, versatile, free from leakage, and bi-directional fluid flow.
