It is suitable for rotary valves that require multiple rotations to com- plete the opening and closing process, such as gate valves, knife gate valves, globe valves, gates, etc. ATMD multi-turn electric actuator with gearbox ATMD type matching umbrella gearbox, which can output greater torque. Suitable for large gate valves, knife gate valves,globe valves, gates, etc. ATMQ part-turn electric actuator ATMQ part-turn actuator output shaft rotates 90 degrees and can accurately control the rotation angle, suitable for rotary valves that can complete the opening and closing process by rotating 90 degrees, such as butterfly valves, ball valves, dampers, etc.

ATSR-EH Series Electro-Hydraulic Actuator( Single Acting )

This product is a small hydraulic power unit equipped with an electro-hydraulic actuator, which is designed and produced independently by our company through the introduction of advanced hydraulic control technology from Europe. The pump, motor, and hydraulic control components in the unit are all high-quality products of international leading brands. The opening/closing of the single-acting power unit ATSR/DCB is driven by hydraulic pressure, and it resets by mechanical spring. The output flow of the power unit is 1.0L/min, 2.15L/min,4.3L/min, and 6.0L/min, respectively, which can be flexibly selected according to the user's switching time requirements of the actuator. The common regulating electro-hydraulic actuator adopts a frequency conversion motor, which can adjust the valve opening degree arbitrarily according to the control signal of 4~20mA, and the adjustment accuracy is about 0.6-0.8%. High precision adjusting type is driven by a high-performance servomotor, and the highest adjustment accuracy can reach about 0.1-0.2%.

AT-EH Series Electro-Hydraulic Actuator

This electro-hydraulic actuator series is an upgrade based on the small AT-EH power unit for personalized complex control of valves. The pump, motor and hydraulic control components in the LPU are all high- quality products from international leading brands. Single-acting series is generally equipped with a single electric control 2/4-way solenoid valve. When the power is suddenly off or ESD signal is received, the actuator can automatically close/open the valve FC (or FO) through the accumulator, and the quickest time can be up to 0.5s. Double-acting of accumulator reset series is generally equipped with a 3/4-way solenoid valve. Under the action of energy storage oil pressure from accumulator, the actuator can be quickly opened and closed in both directions, and valve will remain in position FL during the power breakout. The intelligent adjustment type is equipped with a proportional or servo valve and PLC, and the system can adjust the valve opening degree arbitrarily based on a 4- 20mA control signal, with a maximum accuracy of 0.1% to 0.2%.
