ZDSY electric Y type trap
ZDSY-type electric Y-type trap is composed of a new series of electric actuators and Y-type traps. The two ends of the Y-type trap body are welded. The actuator has two forms of electric opening and electric closing: when the input signal increases, the valve gradually turns from the closed position to the open position for the electric opening type. When the input signal increases, the valve gradually changes from the open position to the closed position.
Principle:
The electric trap receives the current signal input from the regulating instrument, and generates axial thrust through the action of the electric actuator. Through the connecting rod, the flow area of the valve core and the valve seat is changed until the electric actuator is the position feedback signal current and the input Signal current, etc., so as to achieve automatic adjustment of process parameters.
