The Operation Theory of Electric Globe Control Valve

1. Flow Regulation: The Electric Globe Control Valve regulates fluid flow by adjusting the position of a plug or disk in relation to the valve seat. This adjustment controls the flow rate through the valve.
2. Electric Actuation: Electric Globe Control Valves are actuated by an electric motor or actuator, which receives control signals to modulate the valve position. The actuator drives the valve stem to move the plug or disk, regulating the flow accordingly.
3. Feedback Control: Many Electric Globe Control Valves feature feedback mechanisms that provide information on the valve’s position and performance. This feedback enables precise control and monitoring of the valve’s operation.
4. Versatile Applications: Electric Globe Control Valves are used in various industries and applications where accurate flow control is essential, such as HVAC systems, water treatment plants, and industrial processes.

Globe Valve Control

1. Linear Flow Regulation: Globe valves control flow by moving a plug or disk perpendicular to the flow path, creating a linear motion that regulates flow rates accurately.
2. Pressure Regulation: Globe valves are capable of handling high-pressure applications, making them suitable for systems requiring precise pressure regulation.
3. Reliable Shut-Off: Globe valves provide reliable shut-off capabilities, effectively sealing the flow path to prevent leakage when fully closed.
4. Manual and Automated Operation: Globe valves can be operated manually using a handwheel or lever, or automated with electric, pneumatic, or hydraulic actuators for remote control and integration into automated systems.
