Application
Diaphragm valve is a series of sanitary diaphragm valve, it is widely used in wine, dairy products, beverage, food 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.
In order to better meet the process requirements of one or more fluids in different directions, while also considering material and processing costs, valve footprint and layout orientation space, cleaning and sterilization needs, as well as self-discharge and dead leg requirements in pharmaceutical and biological industry, Chengyi can satisfy your needs providing you with reasonable, most cost-effective, and optimal solutions.
The main valve and the outlet valve can be both manually or pneumatically actuated. Different accessories can be supplied.
