QH series products mainly include basic type, resistance type (switch type), intelligent adjustment type, and - body type. There are nearly 100 types of models, which can be connected with different types of ball-type and butterfly valves. The output is in the range of 50NM~2000NM.

The actuator can directly receive the 0-10V, 1-5V, 4-20A DC signals input from the outside, and accurately adjust the opening degree of the valve according to the specific value of the input signal. The new mechanical damping device can eliminate the inertia. Suppresses oscillations to ensure positioning up to (1/00 00). The 4-20mA DC feedback signal is output while adjusting the control to accurately and effectively display the actual opening value of the valve. His body has a LTD liquid crystal display, and 8 indicators can specifically indicate each operation, which makes debugging more convenient and accurate.

A.The indication mechanism of valve position ensures accurate indication of valve opening.

B.The high quality Servo-Controller adopts imported technical grade electronic pants and components. The circuit board with resin plastic package makes shock and humidity resistance better. The unique electronic brake function makes actuator non-surge when positioning.

C.The casing with good quality die cast aluminum alloy is ingenious and artistic.

D.The  limiter of adjustable machine is safe and convenient.

E.The direct installation type mounting Plate is fit with the requirement set forth by lSO5211 and makes linkage with valve simpler, more convenient.
