Electric Actuated Globe Control Valve

Electric Actuated Globe Valve Supplier in South Africa supplies for automated flow regulation and shut-off in industrial piping systems. The globe valve uses a moving disc and seat to control the flow opening, while a multi-turn electric actuator operates the valve stem. On/off and modulating configurations can be selected according to the process-control requirements.

Engineering Design & Operation

The disc moves toward or away from the seat as the stem is operated. This allows a globe valve to regulate flow as well as provide shut-off. An electric actuator enables remote operation through plant control systems.

For modulating service, a suitable positioner or control module can accept signals such as 4–20 mA, depending on the actuator configuration. Limit switches and position feedback can also be provided.

Electric Actuator

Available power supplies can include 24 VDC, 110 VAC, 220/230 VAC and 380 VAC, depending on the actuator model.

Actuator power consumption, output torque, speed and duty rating are size- and model-dependent and should be selected according to the valve's required thrust, pressure, operating frequency and control arrangement. A fixed wattage should therefore not be stated for the complete product range.
