About Hengchun Actuator

CKDYJ Series intelligent part-turn electro-hydraulic actuator is an independently developed mechatronics-hydraulics integrated terminal control device of Yangzhou Hengchun Electronic Co., Ltd. Adopting a modular integrated design, it comes with a built-in hydraulic pump and oil tank, eliminating the need for an external oil supply.

CKDYM series linear stroke hydraulic actuator, an end control unit for industrial automation systems, delivers precise thrust-torque matching for linear valves, and is widely used in power, petrochemical and other industries.

CKQY Gas-over-Oil Actuator is primarily used for the emergency shut-off and line break protection of valves in long-distance oil and gas transmission pipelines. This product extracts gas directly from the pipeline by utilizing pipeline pressure, eliminating the need for any external power supply or other auxiliary power sources. It ensures the rapid shut-off of the gas transmission trunk line in emergency scenarios to safeguard pipeline safety. Nitrogen or compressed air may also be selected as the power source as an alternative.

The BHS series diaphragm-type pneumatic actuators are devices that convert pneumatic pressure signals into linear displacement and output force via elastic diaphragms, and drive the spool movement of valves (e.g., control valves, globe valves) accordingly, so as to realize continuous regulation or on-off control of process parameters such as fluid flow rate, pressure and temperature.
Diaphragm-type pneumatic actuators are classified into spring-return (single-acting) and double-acting types, with the spring-return type commonly applied to emergency shut-off working conditions.
