Pneumatic Sanitary Diaphragm Valve

Product overview:
The pneumatic sanitary diaphragm valve is composed of two parts, the sanitary diaphragm valve and the pneumatic actuator. It takes the compressed air as the driving force. Because the structure of the diaphragm and valve body has corrosion resistant lining and corrosion stuffing structure, throttling element for the elastic diaphragm and the valve body flow smoothly, so the pneumatic diaphragm valve has a negative film force, large flow, no leakage, fire and explosion prevention and convenient and reliable advantages, widely used in industrial automation system in strong acid, alkali, strong corrosion, high viscosity, containing grains, fiber and toxic and not allow pollution of medium flow regulation.

Technical parameters:
(1) Connection: clamp or welding;
(2) Specification: 1/2 "-2"
(3) Control mode: pneumatic;
(4) Valve material: 316L;
(5) Diaphragm material: ethylene propylene rubber, ethylene propylene rubber / ethylene propylene diene rubber (EPDM) / EPDM (three) ethylene propylene rubber;
(6) The use of temperature: ethylene propylene rubber, ethylene propylene rubber, 130 degrees C, PTFE / ethylene propylene diene rubber (EPDM);
(7) The use of pressure: ethylene propylene diene rubber 0 ~ 10bar; PTFE / ethylene propylene diene monomer 0 ~ three ~ 10bar.
(8) The utility model has the advantages that: the device is designed with a regulating and limiting device, which reduces the difficulty of the welding of the bottom of the tank and is compact in structure, and is suitable for small space.

(9) Application: typical application in fermentation tank, mixing tank, filling machine, sterile filter, water equipment, PW, WFI transport and distribution, sterile fluid delivery and CIP, SIP, etc.. Pneumatic diaphragm valve is widely used in pharmaceutical, food and beverage, fluid equipment, cosmetics and other industries.

Working principle：
The closing and opening of the sanitary diaphragm valve is realized by the pressure from the pipeline to enhance the rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pressed down, and the valve passage is closed. When the pressure of the control cavity is discharged to the atmosphere or the downstream pipeline, the diaphragm rises and the valve passage is opened. The valve is not stem, sealing pad, orientation seat, is the only component channel movement of the diaphragm, so there is no rustily, with higher stability. A variety of structural forms, can be applied to a variety of fluid control needs.
