High Quality YP Series Scotch Yoke Actuators Manufacturer and Supplier

YP Series Scotch Yoke Actuators

Short Description:

The YP series is a pneumatic actuator designed and manufactured specifically for quarter-turn (90°) valve automation. It delivers reliable torque output for switching and control applications involving ball valves, butterfly valves, and plug valves.

The actuator features a compact, modular design and is available in two configurations: double-acting and spring-return, offering flexibility for both fail-safe and non-fail-safe operation. Standard torque output ranges cover a wide spectrum to suit various valve sizes and pressure classes.

Product Advantages

Modular design—improves efficiency and safety.

Cost advantage—designed according to valve torque requirements, reducing additional costs.

Reduced maintenance costs—corrosion-resistant internal coating and surface paint.

Improved safety—no risk of accidental spring discharge.

Modular Solutions

The system is primarily divided into: power modules, drive modules, and spring modules.

This solution offers exceptional flexibility. Modules can be easily installed and removed through simple plug-and-play and bolt-fastening methods.

Longer Cycle Life

The STARD YP series modular actuators do not have external rods, which prevents rod failure caused by external factors such as corrosion or impact.

The actuators feature protective internal and external coatings to ensure reliable operation in harsh environments.

The copper slider structure improves contact between the pin and track to increase load capacity and wear resistance, extending service life.

Increased Safety

STARD modular actuators offer maximum safety for spring-return drives.

In our latest design, the spring does not exert any pressure on the end cap of the actuator. The entire spring module is pre-compressed prior to assembly, effectively preventing the possibility of the compression spring popping out of the spring barrel and causing injury
