一．Product Introduction
The heavy duty rotary actuator are available as pneumatic or hydraulic scotch yoke actuators for 90 degree angular valves, dampers or any device.BG series is accompanied by a complete sets of accessories modular, involving side-mounted handwheel, jackscrew & hydraulic overrides, filter/regulater/gauge, limit switches, solenoids valve and positioners, etc. The Heavy duty rotary actuator used in various industries like chemical, refining, pipeline, pharmaceutical, water processing, offshore, etc.
二．Product Features
1. Modular design facilitates on-site configuration, maintenance, and inventory management.
2. The safety design ensures safe operation with a fully enclosed spring module.
3. The machining accuracy is guaranteed, as the housing is processed and formed in a single pass by a CNC machining center.
4. Excellent surface corrosion resistance is achieved through hard chrome plating on the cylinder and piston rod, enhancing corrosion resistance and service life.
5. Efficient and durable, the design features low friction and self-lubricating components for dynamic transmission and sealing.
6. The rated torque output range spans from 100Nm to over 500,000Nm.
7. Wide temperature range coverage includes ultra-low temperature (-60°C), low temperature (-40°C), standard type (-20°C), and high temperature (+150°C).
8. Optional manual operating devices are available, including screw, bevel gear, and hydraulic options (side-mounted handwheel, bevel gear manual override, and hydraulic manual override).
