Features
- The YHD single acting hydraulic actuator is driven using a hydraulic power transmission system that features a compact structure, steady performance, low energy consumption and low noise levels.
- The YHD hydraulic actuator uses butterfly springs, which produce a larger driving force when closing in order to reduce the valve closing time.
- An adjusting screw is added to the spring end of the YHD hydraulic actuator in order to adjust the open valve position.
- The YHD hydraulic actuator can be submerged for installation, making operation convenient.
- An emergency valve block can be coordinated with the emergency hand pump to conduct emergency operations on valves when the system fails.
- YHD hydraulic actuator uses a modular and integrated design, with functions customizable to customer needs.
- The main body of the YHD hydraulic actuator is designed with sectional structure, and the oil tank seals can be directly changed, making maintenance easy.
Options
- Manual worm gear: The YHD hydraulic actuator can be operated manually during power failures.
- Special modular valve block: The YHD hydraulic actuator is equipped with a special modular valve block, which can conduct emergency operation.
- Special connection mode: Special connection mode is convenient to connect micropower unit.
