The PD series Linear Motion Actuator is a compact and light multi-spring type high-performance/high - power diaphragm-actuator. This actuator balances the force generated by the pressure applied to the diaphragm and the force of the compressed spring to control the output and reach the correct set position. Combined with a Control Valve with Linear Motion Stem, this PD series actuator is suitable for modulating or on-off services.

PP series actuators, double acting, or spring return (single acting) types provide a wide range of outputs and are designed to meet the most common applications. Manufactured from Carbon Steel bodies, it is suitable for services in poor conditions such as desert areas, power plants, petrochemical plants and the steel industry. Compact and concise Block System Desig for easy installation and maintenance. All PP series use a commonly applied built-in lubrication grease, providing a long life. Connectivity flanges to Stem and Valve can be manufactured in a variety of applications to meet the specific needs of all customers

• Wide Range of Options – With a wide range of options and accessories, the PP series is ideal for any application requiring high output and easy maintenance.
• Compact and Lightweight – Simple, next-generation design systems make PP series very small and light.
• Simple Maintenance – Easily perform routine maintenance. The PP series spring cylinder actuator is provided with a Block system design to facilitate access to all internal components.
• Simple Parts – Easy to purchase Spare parts from PP series Cylinder actuator Soft -goods parts that use standard O-Ring for both static and dynamic seals.
• Long Service Life – The rigidly designed casing is thick and flexible iron construction provides stability, corrosion protection and deformation protection in the event of excessive pressure.
• Cold Service Application – Enhanced product specifications for PP series cylinder actuators of all sizes ensure performance up to -40℃ if required.
• Positive Connections – Split Block Stem connections provide robust behavioral delivery while making it easy to mount. Minimize connection to ensure correct valve position due to Backlash.
• Compact & Light – PP series is much smaller and lighter than traditional actuators compared to Air Supply Pressure with high Multi-Spring and Single Spring.
