Product introduction
The pneumatic control valve is composed of a pneumatic multi elastic diaphragm actuator and a low flow resistance single seat control valve. The new actuator is low in height, light in weight, simple in equipment, compact in structure, smooth in flow passage, and has a large flow coefficient. The pneumatic control valve has stable operation, reliable action characteristics, small valve seat leakage, accurate flow characteristics, wide adjustable range and other characteristics, and has achieved high-quality control effect in wide application.
Pneumatic control valves include standard type, regulating cut-off type, bellows seal type, jacket insulation type, etc. The applicable liquid temperature ranges from - 200C ° to+560C *. It is applicable to the occasions where the leakage is strictly required, the pressure difference between the front and back of the valve is low, the viscosity is constant and there is a small amount of fiber medium.
Common forms:
It can be divided into normally open air close type and normally closed air open type according to the different switching modes. The air close valve is composed of a positive acting actuator and a valve. When the input signal pressure changes from the lower limit value to the upper limit value, the valve will be fully opened to fully closed. The air to open valve is composed of reaction actuator and valve. When the input signal pressure changes from the lower limit value to the upper limit value, the valve will be fully closed to fully open.
