Three way Electric control valve

Date: 30 Oct 2009

Detailed Product Description :

1)  Electrical regulating valve consists of two parts, straight stroke electrical actuator and regulating mechanism. You could find three structural types of valve from fig.1, 2 
2)  For structure and principle of electrical actuator, please refer to related instructions of the product. .
3)  The apparatus is equipped with electrical operator and could realize two directions no disturbance switch of manual and automatic. It also could be used as remote controller. With indicating lamps of manual, automatic and ammeter, it could indicate valve level.
4)  There are two action methods for one seat valve, electric open and electric close. When input signal increase, valve turns from closing position to opening position gradually, it is electric open type. When input signal increase, valve turn from open position to closing position gradually, it is electric close type. Provide according to electric open type ex. Works.
5)  For three way valve, because open and close in valve exist at the same time, so it has no difference of electric open and electric close.
6)  Working principle: electrical regulating valve receive inputting current signal from regulating apparatus, action through electrical actuator, occur axial pushing force. Change flow area between valve core and valve seat ( or valve plug ) through connecting bar till feedback signal  current of at position of electrical actuator equal to input signal current to reach the purpose of adjust technological parameters or change flowing direction of medium automatically.
