electric valve is composed of three 3610L series electric actuators and three way control mechanism. Electric actuator in a servo system, no need of a servo amplifier, have spread into the signal and power source control operation, simple wiring. Adjusting mechanism is combined and split two ways, can replace the two two valve and a three way pipe has been widely used in some occasions. Two commonly used in heat exchanger and regulation of simple ratio regulation.
