Electric Actuated Globe Valve
Introductions
The Electric Actuated Globe Valve is designed to use valve stem pressure to tightly fit the sealing face of the valve clack and the sealing face of the valve seat to cut off the medium, making it a forced seal valve. The flow direction of the medium in the globe valve is allowed to flow in only one direction, either “low in and high out” or “high in and low out”, and the valve must be installed in the correct direction. The valve comes in three different structures: straight-through type, direct flow type, and right angle type. When the Electric Actuated Globe Valve is open, the flow reaches its maximum when the opening height of the valve clack is up to 25% ~ 30% of nominal diameter, indicating that the valve has reached its fully open position. These features make the valve ideal for use in various industries, including oil and gas, chemical processing, water treatment, and power generation, for flow, pressure, and temperature control applications.

How Electric Actuated Globe Valves Work
Electric Actuated Globe Valves are made up of a valve body, a valve stem, a valve disk, and an electric actuator. The electric actuator is connected to the valve stem, which moves the valve disk to control the flow of fluid. The electric actuator receives signals from a control system, which determines the amount of fluid that needs to flow through the pipeline.
The electric actuator can be programmed to open and close the valve at specific times or in response to specific events. For example, the valve can be set to open when the fluid pressure reaches a certain level or close when the fluid level drops below a specific threshold. This makes the valve ideal for use in systems that require precise control over fluid flow.
Benefits of Electric Actuated Globe Valves
Electric Actuated Globe Valves offer several advantages over manual globe valves. Some of the benefits include:
- Automation: The electric actuation feature allows for automatic control of the valve, reducing the need for manual intervention.
- Efficiency: Electric Actuated Globe Valves are more efficient than manual valves because they can be programmed to open and close at specific times, reducing the amount of time the valve is open.
- Reliability: Electric Actuated Globe Valves are more reliable than manual valves because the electric actuator can detect and respond to changes in fluid pressure or flow.
- Safety: Electric Actuated Globe Valves are safer than manual valves because they can be programmed to shut off automatically in case of an emergency.
Advanstages of Electric Actuated Globe Valves
Electric actuated globe valves are becoming increasingly popular for regulating fluid flow in pipelines. Their automation reduces the need for manual intervention, making them efficient and reliable. These valves can be programmed to open and close at specific times or in response to specific events, making them ideal for systems that require precise control over fluid flow.
Electric actuated globe valves are energy efficient because they can be programmed to open and close at specific times. They are more reliable than manual valves because the electric actuator can detect and respond to changes in fluid pressure or flow. They are also safer because they can be programmed to shut off automatically in case of an emergency.
These valves are widely used in industries such as oil and gas, chemical processing, water treatment, and power generation for controlling flow, pressure, and temperature.
Applications of Electric Actuated Globe Valves
Electric Actuated Globe Valves are used in a wide range of industries, including oil and gas, chemical processing, water treatment, and power generation. Some of the common applications of Electric Actuated Globe Valves include:
- Flow control: Electric Actuated Globe Valves are used to regulate the flow of fluids in pipelines.
- Pressure control: Electric Actuated Globe Valves are used to control the pressure of fluids in pipelines.
- Temperature control: Electric Actuated Globe Valves are used to control the temperature of fluids in pipelines.
Conclusion
Electric Actuated Globe Valves are a modern and efficient alternative to traditional manual globe valves. They offer several benefits, including automation, efficiency, reliability, and safety. Electric Actuated Globe Valves are widely used in various industries, including oil and gas, chemical processing, water treatment, and power generation, for flow, pressure, and temperature control applications.
