ZJHPF46 series pneumatic lining fluorine seat control valve is composed of pneumatic diaphragm actuator directly through the single-seat fluorination control valve body. Pneumatic lining fluorine control valve body corrosive medium contact parts are used corrosion-resistant, anti-aging polyfluorinated ethylene propylene, high-pressure lining fluorine plastic technology, but also using PTFE bellows seal. Pneumatic lining fluorine single-seat regulating valve has the regulation of acid, alkali and other high-strength corrosive media and poisonous volatile gas and liquid medium flow. Therefore, pneumatic lining fluorine regulating valve is widely used in chemical, metallurgical, pharmaceutical and other industries. The main features of the product:
(1) Corrosion resistance: Valve body cavity, valve core, valve seat, and all packages are lined with 3mm thick PTFE, which can withstand strong corrosive fluids. The
(2) Good sealing performance: Double sealing with PTFE bellows and packing. The
(3) Less leakage: Because the leakage of the valve core and valve seat is a soft seal, it is much lower than the national IV standard. The
(4) High adjustment accuracy: The use of compact pneumatic actuators and electric actuators is small and light.
