Part Turn Actuator

Part-turn actuators are 90° driving mechanisms that can be powered by compressed air or hydraulic oil from an external source to convert the linear motion of a reciprocating bar into rotational motion. Scotch yoke part-turn actuators are specifically designed to rotate heavy loads and deliver high torque output. Valves typically require higher torque at the beginning and end of their stroke, making the Scotch yoke actuator an ideal solution to meet this requirement.

The control system is a crucial component of the actuator, capable of fulfilling various functional needs of the actuator.

With extensive experience, Bigtork can cater to various user needs in switch control, frequent adjustment control, and ESD (emergency shutdown) control. Bigtork offers industry-leading control accessories and components, designed and manufactured internally, including limit switches, quick exhaust valves, hydraulic manual override modules, rupture disc protection systems, and stroke limiting devices.

Bigtork can provide a comprehensive control system encompassing the following four solutions: partial stroke testing (PST) for fire protection systems, rapid shutdown adaptive actuators, and control schemes tailored for harsh working conditions.

Excellent Durability

Part Turn Actuator utilizes high-strength stainless steel material, undergoing precise forging and heat treatment processes, ensuring its mechanical structure can endure up to 50,000 cycles of operation without deformation or wear. This enhanced durability stems from the material's high fatigue resistance and excellent corrosion resistance, allowing the product to maintain a long service life even in harsh industrial environments. Compared to similar products made of ordinary materials in the market, the Mean Time Between Failures (MTBF) is extended by 30%.

Advanced Waterproof Sealing

The specially designed waterproof sealing system employs double O-rings and special waterproof coating technology, effectively preventing the ingress of moisture and humidity, achieving an IP67 protection rating. This means that even in damp, dusty, or outdoor exposed environments, Part Turn Actuator can keep its internal electronic components dry and safe, avoiding the risk of short circuits or corrosion. Compared to traditional sealing methods, our waterproof technology reduces water permeability by 95%, significantly improving the product's environmental adaptability and reliability.

High Efficiency and Low Energy Consumption

Adopting advanced permanent magnet synchronous motor technology, Part Turn Actuator delivers powerful torque output while reducing energy consumption by approximately 30% compared to traditional asynchronous motors.

Modular Design

Part Turn Actuator adopts a modular design concept, with simple connections between components, making them easy to disassemble and replace. This design not only facilitates rapid installation and commissioning at the site but also reduces the complexity and time cost of later maintenance. Modular design extends the maintenance cycle by 25%, further enhancing the operational efficiency and stability of the overall system.
