Four fluorine pneumatic membrane lining single-seat regulating characteristics of pneumatic valve

four fluorine pneumatic membrane lining single-seat regulating pneumatic valve, is the execution units in the automatic control instrument. It consists of pneumatic diaphragm actuators and direct single seat pad fluorine plastic pneumatic valve is composed of two parts. Because of the pneumatic valve contact medium parts adopt high pressure injection molding process, the liner capable of corrosion and ageing resistance of fep ( F) With ptfe bellows seal, and thus the pneumatic valve is widely used in chemical, petroleum, metallurgy, medicine, electric power industries in the strong acid, alkali corrosion medium and the medium of the toxic and volatile gas, process control. Corrosion resistance: pneumatic valve body cavity, pneumatic valve, pneumatic valve seat, pneumatic valve rod are stainless steel, acid, alkali, strong corrosion resistance. Good seal performance, using four ethylene material of corrugated pipe and double seal packing, ensure no leakage. Small amount of leakage, the pneumatic, pneumatic valve core is soft seating, so the leakage is lower than the national level IV standard. Using light small spring actuator, small volume, light weight, high precision of adjustment.
