UPVC Flange Type Diaphragm Valve DN15-300

Carrying Your Dream To The World Quality is Life

We Are Leading Company In This Field, We Provide Specific Solutions For Our Every Customers
A diaphragm valve is a type of valve that uses a flexible diaphragm to separate the flow passage from the valve's operating mechanism. The diaphragm, which is typically made of rubber or another flexible material, is connected to a stem that passes through the valve body. When the stem is moved up or down, it compresses or decompresses the diaphragm, which in turn opens or closes the flow passage.
Diaphragm valves are often used in applications where there is a need to isolate the flow passage from the valve's operating mechanism in order to prevent contamination or leakage. They are widely used in chemical, pharmaceutical, food, and beverage industries. Also, it is widely used in cleanrooms, sanitary and sterile applications. They can also be used in applications where the fluid being controlled is abrasive or corrosive, as the diaphragm can be made of materials that are resistant to these conditions.
Diaphragm valves are designed to provide a long service life and low cost of ownership. A wide range of materials, connections and flow ratings tests are available. Diaphragm Valves offer an excellent compromise between reliability, cost and performance.
