Product description
Zmapf46 pneumatic fluorine single-seat regulating valve is diaphragm actuator and corrosion through low flow resistance single-seat valve by the spring gas component, the inner wall of the valve body single-seat valve in contact with the fluid and valve are high-pressure injection molding process, lined with corrosion resistance, aging resistance of the fluorinated ethylene propylene (F46) plastic, and the use of PTFE bellows seal, has the advantages of good sealing performance, sensitive action, fluid channel was streamlined s, the pressure drop loss, valve capacity, accurate flow characteristics, equipped with electric - gas valve positioning or pneumatic valve positioner, can realize the control of the automatic adjustment of road fluid process pipe, control is widely used in acid, alkali and other strong corrosive media and toxic, volatile, easy penetration, gas, liquid medium.
The characteristics of ■:
1 gas regulation valve fluorine single-seat is executing unit automation control system instrument, the electric - gas valve positioner, the electrical signal and compressed air as a driving force, to accept the input of a control system of 0-10mA
DC or 4-20mA
DC current signal, the regulator will be compressed air, into the air pressure signal input, with straight stroke output thrust to change the valve opening displacement, achieve the process parameters on the fluid medium precision control
