一．Product Introduction

WYE series scotch yoke pneumatic piston actuator are designed in many different model number combinations of actuator sizes, cylinder diameters. The scotch and yoke actuator can provide a wide torque output range from 110Nm to 500000Nm, which the high torque can support big size ball valve, butterfly valve etc quarter turn valves.These pneumatic piston actuators can be used for on/off application and the special torque characteristic make them ideal for control applications.

二．Product Features

1. Wide Torque Range & High Versatility

   It offers a broad torque output range from 110Nm to 500,000Nm, which can support large-size ball valves, butterfly valves, and other quarter-turn valves, making it suitable for valves of different diameters and pressure ratings, especially advantageous in large pipeline systems.

2. Dual Application Capability

   It is applicable for both on/off and control applications. Its unique torque characteristic makes it ideal for precise control of valve openings to regulate flow, pressure, and other process parameters.

3. Efficient Scotch Yoke Mechanism

   Adopting the Scotch Yoke structure, it efficiently converts the linear motion of the piston into 90° angular rotation, ensuring high transmission efficiency and stable power output, even under high-load conditions.

4. Modular Design for Flexibility

   It comes in various model combinations of actuator sizes and cylinder diameters, allowing flexible configuration based on actual needs. It also facilitates later maintenance, spare parts replacement, and inventory management.

5. Robust Construction & Long Durability

   Key components like the cylinder are made of high-strength materials and precision-machined to ensure structural stability. It can operate stably for a long time in harsh industrial environments such as chemical, petrochemical, and pipeline industries, with excellent impact and vibration resistance.

6. Potential for Precision Control

   When paired with accessories like positioners, it can achieve high-precision control of valve openings, with a control accuracy of up to ±1%, meeting the precise regulation requirements of process industries for process parameters.

7. Easy Integration & Mounting

   It complies with universal mounting standards (e.g., ISO 5211), enabling convenient integration with various quarter-turn valves, significantly reducing installation time and engineering implementation difficulty.
