Product Description
Design
Armed with the idea of the small in volume, light in weight and novel in pattern, we designed and developed the CHINAMFG series gear operators which are wildly applied in the area of valve automation control. These kinds of products were specially designed used for butterfly valve, ball valve and plug valve together with YSPHA series pneumatic actuator
Feature
1, Easy connection: There are 2 keyway apart 90¡ In the inner hole of worm gear so as to be convenient for customer to choose relative position between gear operator and valve.
2, Easy operating: Pull out the position pin and rotate off center device with 180¡ To realize pneumatic drive by positioning pin acted or to realize manual drive in the opposite way.
3, Dustproof and waterproof: The gear operator is filled with special lubricant before leaving the factory. It is CHINAMFG sealed with valve after installation possessing dustproof and waterproof function with protecting grade IP65.
4, Many Output torques: It consists of a series of products, so output torque matches with all kinds of pneumatic devices and valves.
Operating principle
1, Assembling procedures: The bottom of gear operator should be connected with valve, bracket surface connected with cylinder (actuator), valve stem go through the inner hole of worm gear and the square on the end of stem matches with square hole of cylinder (actuator).
2, Operating procedures: The cylinder (actuator) drives valve stem and worm gear rotating together when pneumatic drive and worm shaft meshes with worm gear to drive valve stem rotating along with piston of cylinder (actuator) moving when manual drive. When pneumatic drive, pull out the pneumatic drive by worm gear rotating following with pneumatic valve stem. Just make the worm shaft mesh to realize manual drive.

Can I Use Synthetic Oil in My Gearbox?
Yes, you can use synthetic oil in your gearbox, and in many cases, it can offer several advantages over conventional mineral-based oils:
- Improved Temperature Stability: Synthetic oils typically have a higher resistance to thermal breakdown, making them suitable for gearboxes that operate at high temperatures.
- Enhanced Lubrication: Synthetic oils often have superior lubrication properties, providing better protection against friction, wear, and component damage.
- Extended Oil Change Intervals: Synthetic oils can often withstand longer operating periods without losing their effectiveness, reducing the frequency of oil changes and maintenance.
- Reduced Viscosity Changes: Synthetic oils are less prone to viscosity changes at different temperatures, ensuring consistent lubrication performance in varying conditions.
- Lower Friction and Energy Loss: The smoother molecular structure of synthetic oils can lead to reduced internal friction, potentially improving gearbox efficiency and performance.
- Cold Weather Performance: Synthetic oils generally flow better at low temperatures, making them suitable for gearboxes operating in cold climates.
- Protection Against Oxidation: Synthetic oils often have better resistance to oxidation, helping to prevent the formation of sludge and deposits that can impact gearbox performance.
However, before switching to synthetic oil, it’s important to consider the manufacturer’s recommendations and specifications for your specific gearbox model. Some gearboxes may have specific requirements or restrictions on the type of lubricant to use. If the manufacturer approves the use of synthetic oil, it can be a beneficial choice, but if not, sticking to the recommended oil type is crucial to ensure proper gearbox function and warranty coverage.
