Electric Motorized Ball Valve

Electric Motorized Ball Valves

Electric motorized ball valves combine a quarter-turn ball valve with an electric actuator for remote operation in industrial piping systems. Depending on the configuration, they support on/off isolation or modulating flow control in water treatment, HVAC, process piping, and OEM equipment.

Key Features & Benefits

Remote Operation

Supports automated valve opening and closing through compatible PLCs, control panels, and building management systems.

On/Off or Modulating Control

On/off models provide pipeline isolation, while compatible modulating configurations support flow adjustment using specified control signals.

Flexible Material Selection

Body, ball, stem, and seat materials can be selected according to fluid compatibility, pressure, and temperature requirements.

Optional Actuator Functions

Limit switches, position feedback, manual override, and fail-safe accessories are available depending on the actuator model.

Applications

Water Treatment

Automated isolation in water distribution, filtration, and compatible chemical dosing systems.

HVAC Systems

On/off switching or modulating control in compatible heating and chilled-water circuits.

Industrial Process & OEM Equipment

Remote valve operation in process skids, machinery, and automated fluid-handling systems.

Material & Control Selection

Valve Materials: Select body, ball, stem, and seat materials based on the medium's chemical properties, operating temperature, and pressure.

Actuator Sizing: Confirm valve operating torque, differential pressure, operating frequency, and actuator output torque.

Control Requirements: Specify supply voltage, On/Off or Modulating operation, input signal, and position feedback.

Power-Failure Response: Define whether the valve should remain in its last position or move to a specified safe position after power loss.

Manufacturing & Quality Control

Dimensional Inspection

Verify valve dimensions, end connections, and actuator mounting interfaces against applicable drawings.

Pressure & Leakage Testing

Conduct shell and seat testing according to the applicable valve design and test requirements.

Technical Documentation

Datasheets, dimensional drawings, wiring diagrams, pressure-test records, and material certificates can be provided according to model and order requirements.

Customization & RFQ Requirements

Valve Specifications

Size, valve configuration, pressure rating, end connection, and material requirements.

Operating Conditions

Fluid medium, operating temperature, working pressure, differential pressure, and required flow rate.

Electrical Configuration

Supply voltage, control mode, signal type, feedback requirements, and power-failure behavior.

Compliance & Documentation

Applicable standards, certification requirements, material reports, and inspection documents.

Frequently Asked Questions

Q: What is the difference between an electric motorized ball valve and a manual ball valve?

A: A manual ball valve requires hand or gearbox operation, while an electric motorized ball valve uses an electric actuator for remote or automated control.

Q: Can an electric motorized ball valve regulate flow?

A: Yes, when configured with a compatible modulating actuator and suitable valve flow characteristics. Standard On/Off models are primarily intended for isolation.

Q: What happens if the power supply fails?

A: The valve response depends on the actuator configuration. Standard actuators may remain in their last position, while specified backup or spring-return options can provide a defined return action.

Q: How do I select the correct electric actuator?

A: Consider valve operating torque, differential pressure, operating frequency, supply voltage, control requirements, and mounting compatibility. Confirm actuator sizing against the valve manufacturer's technical data before ordering.

Q: What documents should I request before purchase?

A: Request the valve and actuator datasheets, dimensional drawings, wiring diagrams, applicable pressure and leakage test records, and required material or compliance certificates.
