There are two kinds of switch type and intelligent type, butterfly valve and CWR actuator matching, input control signal (4~20mADC or 1~5VDC) and single-phase power supply can control the operation, with strong function, small size, light and pleasing, reliable performance, simple matching, flow capacity, especially suitable for the media is thick, containing particles, fiber properties of the occasion. At present, the valve is widely used in food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, power and other industries in the industrial automatic control system.
