Welded Hand-Wheel (200 Or Above) NBR Sealing Materials Suitable For -20℃ ~ 120℃ Working Conditions
1 . Descriptions with Ball Valve Gearbox:
Valve Gearbox is mainly used to cooperate with the starting
actuator, and Valve Gearbox is divided into double-acting actuator
and single-acting actuator
SJ series gear operators
SJ series partial-turn gear operators are widely used in water
plants, chemical plants, and power plants and for general
industrial applications. SJ single-stage models have a speed ratio
varying from 24:1 to 80:1 and torque ranging from 170NM to 2500NM.
Motor-fully enclosed squirrel cage motor, small size, large torque, small inertia, F-class insulation level. The internal thermal protection switch prevents damage to the motor.

3.Quality Control of Valve Gearbox:
1.Installation--The installation dimensions of the bottom of the electric actuator conform to the international standards ISO5211 and DIN3337. The larvae form a square, which is easy to pass linear or 45. installation. The actuator can be installed vertically or horizontally.
2. Circuit-circuit control circuit conforms to single-phase or three-phase power supply standards, with a reasonable and compact layout. The terminal effectively meets the requirements of various additional functions.
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.
