2inch Ductile Iron Handwheel Gear Operator For BUTTERFLY
1 . Descriptions with2inch Handwheel Gear Operator:
Handwheel Gear Operator is mainly used to cooperate with the starting actuator, and 2inch Handwheel Gear Operator is divided into double-acting actuator and single-acting actuator
SLJ series gear operators
This series consists of eight models with the speed ratio varying from 26:1 to 520:1 and the toque ranging from 300NM to 22000NM. The torque difference between every two adjacent models is small, helping to save a lot of costs for customers when selecting a specific product. The clutch gear operator has a torque ranging from 300NM to 22,000NM and is available in 8 models with the speed ratio varying from 26:1 to 520:1.
Shell--refers to the cover is made of hard aluminum alloy, with anodizing treatment and polyester powder coating. High corrosion resistance, waterproof grade is IP67. IP68 and explosion-proof type are optional.

1.Position indicator-installed on the central shaft, used to observe the position of the valve. In order to avoid deposition and facilitate observation, it is designed by convex lens.
2.Heater and thermostat-used to control the temperature inside the actuator to avoid internal humidity
3.Limit switch-two mechanical and electronic dual limit. The mechanical limit screw is adjustable, safe and reliable. The electronic limit switch is an SPDT controlled by a cam. The position of the limit switch can be set accurately and conveniently through simple adjustments.
4. Torque switch-provides overload protection (except OHQ 005/008/010), and when the valve is blocked, the power is automatically cut off to avoid damage to the valve and actuator. (Factory setting, no need for user modification)
5.Self-locking-precision worm gear drives high torque, low noise (up to 50dB) and long service life. The self-locking function prevents reverse rotation, ensuring stability and reliability. The high-efficiency lubricating oil has been added before leaving the factory and no longer needs to be added.
