Application

Diaphragm valve is a series of sanitary diaphragm valve, it is widely used in wine, dairy products, beverage, food, biological and pharmaceutical industries. Achieving the requirement of control and open/close for the pipeline system.

Work principle

The diaphragm valve is normally closed, where the diaphragm clings to the inner cavity of the valve body and closes the pipeline flow path. When the diaphragm valve needs to be cleaned or opened, the stem moves upward by rotating the handwheel manually or driving the pneumatic control actuator, and the spherical diaphragm bends upward, so that the valve is open and reach the requirement of clean and open. The diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the stem and valve core located in the upper part of the diaphragm are not corroded by the medium, thus the packing sealing structure is eliminated and the medium leakage will not occur. Optimized valve body design made the cleaning liquid discharge fully, do not form a retention phenomenon.

Material

Steel parts: 304 stainless steel, 316L stainless steel

Seals: EPDM+PTFE which are made of imported sealing materials. Using the special technology of kemus, a connecting bolt is combined with EPDM/PTFE to form a whole sealing part. The sealing part and contact part of the PTFE material have good cold resistance(-25℃),with long working temperature reaching +130℃ and sterilization temperature 150℃≤30min, which has good tolerance to various chemical agents and excellent wear resistance to fluids.

Standard design

Standard: DIN, 3A, SMS, ISO, etc.

The parts of diaphragm valves:high temp. handwheel or pneumatic head, diaphragm and body which assemble together with bolts and nuts. The entire valve assembly in meticulously. The actuator is manual or pnuematic, the diaphragm made of artificial rubber which can have all kinds of soft and hard degree.
