Pneumatic diaphragm valve is a common fluid control valve, which is widely used in chemical, petroleum, pharmaceutical, food and other industries. Correct sizing can ensure the normal operation of the pneumatic diaphragm valve and avoid some problems, the following is a guide on the selection of Detersen pneumatic diaphragm valve:
OneSelect the material according to the media type:
The materials of pneumatic diaphragm valves include steel, stainless steel, plastic, etc., and the appropriate material should be selected according to the type and nature of the medium.
IISelect the model according to the working pressure and temperature:
The working pressure and temperature range of the pneumatic diaphragm valve is limited, and the selection should ensure that it meets the actual working conditions and select the corresponding model.
IIISelect the size according to the medium flow rate and the diameter of the valve:
The size of the pneumatic diaphragm valve is determined according to the flow rate of the medium and the diameter of the valve, and the appropriate size should be selected according to the actual needs.
FourthConsider the corrosiveness and viscosity of the medium:
Some media have strong corrosiveness and high viscosity, such as volatile organic compounds, high-temperature grease, etc., which require a special valve structure.
FiveConsider the use environment and safety requirements:
The use environment and safety requirements of pneumatic diaphragm valves should also be included in the selection consideration, if there is a first-class gas, flammable substances and other environments, it is necessary to choose valves with explosion-proof, antistatic and other special structures.
SixConsider maintenance and repair:
The maintenance and repair of pneumatic diaphragm valves are very important, and components that are easy to maintain and replace should be selected to improve the reliability and maintenance efficiency of the equipment.
The above are some guidelines for the selection of pneumatic diaphragm valves, and it is necessary to conduct a comprehensive evaluation according to the actual needs before selection, and select the appropriate model of pneumatic diaphragm valves to ensure the efficient, stable and safe operation of the equipment.
