Equiped with an automatic control switch, Zhonghuan's pneumatic actuator uses nitrogen gas or natural gas as a power source. It is widely used in petroleum, chemical, metallurgy, food, and other industrials that requires control of valves. It can drive ball valves, butterfly valves, plug valves, and any 90 degree rotational type valve.

-
2Wear Resistant
A piston bar and guiding bar with fine surface treatment are combined with a self-lubricating bearing, ensuring superior abrasion resistance and extending the service life of all sliding parts.
-
3High Efficiency
The piston bar and guiding bar with fine surface treatment are combined with a self-lubricating bearing, ensuring superior abrasion resistance and extending the service life of all sliding parts.
-
4Corrosion Resistant
SF-series actuators incorporate more than 3 layers of protective coatings which can withstand severe service conditions. The inner surface of the gas cylinder is coated with PTFE to enhance its corrosion resistance and self-lubricating performance.

6Safe Spring Module
To ensure the safety of the operator during the installation and maintenance of the spring module, the module is designed so that it can only be disengaged as a complete unit from the actuator along the axial of the cylinder module, avoiding possible accidental damage from the spring force on personnel or the actuator.
