Stainless steel electric ( T/L) The 3-way regulating pneumatic ball valve

Electric 3-way regulating pneumatic ball valve is a kind of rotary type cutting regulation pneumatic valve, mainly used for cutting in line, distribution, and change the flow direction of medium, has closed tight, compact structure, light weight, convenient maintenance, widely used in gas, liquid, steam, oil and other corrosive medium pipeline automatic control. Electric 3-way regulating pneumatic ball valve has a T shape and L shape, T shape can make three orthogonal pipe mutual unicom and cut off the third passage, shunt, confluence role, L tee ball type pneumatic valve can only connect two orthogonal pipeline, cannot maintain the third pipeline connected each other, only plays a role of allocation.



electric 3-way regulating pneumatic ball valve technical indicators:



1, 0 ~ 10 ma receiving control signals. 4 ~ 20 ma。 DC or 1 ~ 5 v. 直流;

2, the key choice: ( 1) And the input signal is interrupted: & other; Interrupt & throughout; The modal ( Open, stop, close) ； ( 2) , is the inverse movement choice; ( 3) , choice of control accuracy.

3, electric device full open and full closed position automatic positioning calibration, convenient and accurate.

4, according to the input signal and the step of intelligent electric actuator position from the adjustment of automatic positioning, restrain oscillation, high precision.

5, 4 ~ 20 ma output electric actuator position signal. DC electric device full closed and open.
