Benefits Of COVNA Explosion-proof Electric Valve Actuator:
COVNA explosion-proof electric actuator provides you with a safe and reliable fluid control solution. This electric actuator contains an explosion-proof module, which effectively guarantees the safety of the valve and the safety of the project. Widely used in dangerous industries, such as oil pipelines, natural gas pipelines, shipbuilding and so on. Use with ball valve, butterfly valve, gate valve or globe valve to help you realize industrial automation and improve the safety of your project.
Features Of COVNA Explosion-proof Electric Valve Actuator:
- High torque up to 2000Nm
- It has a protection class being IP65, NEMA4 and 6. And it is also optional for ip68 and the explosion-proof type
- Fully enclosed squirrel-cage motor has a samll size, a large torque and a small inertia force, with an insulation class f and a built-in thermal protection switch to prevent damages to the motor caused by overheating
- Overloading protection & manual control are available
- A self-locking function to prevent reversion
- The indicator is mounted on the central shaft and used to observe the valve position

Purchase Guide
- Confirm the valve size, valve material and working pressure. Those 3 points will affect the torque of the actuator. So please help to confirm those 3 points then we will advise the right model for you to allow your valve to open/close smoothly. On the other hand, if you know the torque needed, it is a great help for us to select a model
- Confirm the working temperature. If the working temperature is high, we will suggest the actuator with a bracket to protect the actuator far from the medium to ensure the lifespan of the actuator
- Confirm the size of the platform and coupling. We will help you confirm the connection size step by step. And make sure the actuator and valve are properly connected
