HPY Series

The HPY series scotch yoke type pneumatic actuator is an industrial part-turn valve drive mechanism developed with a modular structure design. Utilizing compressed air as the power source, it allows flexible replacement of pneumatic modules or spring return modules on both sides of the housing, enabling both double-acting and single-acting functions. The actuator can be equipped with optional accessories such as hydraulic manual override, solenoid valves, and limit switches, and is widely suitable for 0~90° rotating valves including ball valves, butterfly valves, and plug valves.

Product Introduction

Modular Design

The HPY series scotch yoke type pneumatic actuator employs a modular architecture that systematically integrates functional components including transmission, cylinder, spring, and manual override modules. This design provides exceptional configuration flexibility, supporting both double-acting and single-acting operation modes to address diverse application scenarios.

Corrosion and Wear Resistance

The HPY series scotch yoke type pneumatic actuator features specially treated piston rods, guide rods, and self-lubricating bearings with advanced surface treatments that significantly enhance wear and corrosion resistance. The housing is coated with a high-performance protective layer, while the inner bore is treated with a PTFE coating, collectively ensuring superior overall corrosion resistance.

Excellent Protection Performance

The HPY series scotch yoke type pneumatic actuator meets IP67 protection standard, with all connection points equipped with high-performance O-rings and sealing gaskets. This design effectively prevents external moisture and contaminating dust from entering the actuator interior, ensuring stable and reliable performance with extended service life.

Universal Connection Standard

The actuator's output accessories comply with NAMUR standards, and its mounting dimensions for valve connection meet ISO 5211 requirements, giving the HPY series actuators excellent interchangeability.
