Product Description
Product profile:Category: Electric ActuatorProduct name: Lunar Phase Series Electric Actuator
The lunar phase series electric actuator in the automatic adjustment system according to the adjustment instrument signal change perform 0 ~ 180° or 0 ~ 360° rotation to drive the valve to control the opening.
Powered by alternating current or direct current it can directly receive digital signals from computer or instrument 4-20madc or 1-5vdc standard analog signals to realize intelligent control and accurate positioning of electric valves.
Electric actuator and accessories with double limit overload overheating protection good safety performance.A variety of speeds are available for full travel time.
Various Angle stroke valves (ball valve butterfly valve plug valve etc.) and valves together constitute electric control valve electric ball valve electric butterfly valve and other industrial automatic electric valves.
