【ZJHPF46 lining fluorine bellows regulating valve - Product Description】

 Fluorine bellows valve is a pneumatic diaphragm actuator and through the single-seat fluorine plastic valve is composed of two parts. Lining fluorine bellows control valve parts exposed to corrosive media are used corrosion-resistant, anti-aging of FEP, high pressure lined plastic process, but also the use of PTFE bellows seal. Lined fluorine bellows valve with acid, alkali, aqua regia and other highly corrosive media and toxic volatile gases, liquid media flow regulation. Therefore widely used in chemical industry, metallurgy, medicine and other industries.

【ZJHPF46 lining fluorine bellows regulating valve - Product Features】

 1, good corrosion resistance: body cavity, the valve core, seat, are lined with 3mm thick poly FEP, resistant to strong corrosive fluids. 
 2, good sealing performance: PTFE bellows and packing double seal. 
 3, a small amount of leakage: As the spool, seat with a soft seal to ensure that no leakage. 
 4, high regulation accuracy: the use of small pneumatic actuators and electric actuators, small size, light weight.
