The pneumatic diaphragm valve is composed of two parts: the diaphragm valve and the pneumatic actuator. It uses compressed air as power and is used to regulate the flow of fluid media in the process pipeline.
Due to the adoption of a valve body with a corrosion-resistant lining and a corrosion-resistant diaphragm in its structure, a structure without a stuffing box, an elastic diaphragm as the throttling element, and a smooth flow path in the valve body, the pneumatic diaphragm valve has the advantages of low resistance, large flow, no external leakage, convenience and reliability, as well as fire and explosion prevention. It is widely applicable to the flow regulation of strong acids, strong alkalis, highly corrosive, high-viscosity, granular, fibrous, toxic and non-polluting media in industrial automation systems.
The closing and opening of the diaphragm valve are achieved by the pressure from the pipeline acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pushed down, closing the valve passage. When the pressure in the control chamber is discharged to the atmosphere or downstream pipeline, the diaphragm rises and the valve passage is opened. The valve has no valve stem, gasket, directional seat, etc. The only moving part in the channel is the diaphragm, so there is no rusting or seizing phenomenon, and it has higher stability. With various structural and control forms, it can be applied to a wide range of fluid control requirements.
It is widely applicable to the flow regulation of strong acids, strong alkalis, highly corrosive, high-viscosity, granular, fibrous, toxic and non-polluting media in industrial automation systems.
Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’ is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
Structural characteristics
The diaphragm made of rubber seal has good sealing performance.
2. Due to the limitations of diaphragm materials, diaphragm valves are suitable for low-pressure and relatively low-temperature applications.
3. Diaphragm valves can be classified into six types according to their structural forms: roof type, direct current type, stop type, straight-through type, gate plate type and right-angle type. The connection form is usually flange connection; According to the driving mode, it can be divided into three types: manual, electric and pneumatic. Among them, pneumatic drive is further classified into three types: normally open type, normally closed type and reciprocating type.
4. Generally, pneumatic diaphragm valves are not suitable for use in pipelines with temperatures above 60 degrees or for transporting organic solvents and strong oxidizing media, nor should they be used in pipelines with higher pressure.
