How do I select an electric actuated ball valve?

Confirm valve type, size, body and seat material, medium, pressure, temperature, required operating torque, ISO 5211 interface, voltage, on-off or modulating function, control signal, feedback, duty cycle and any project certifications.

What is the difference between on-off and modulating electric ball valves?

An on-off package moves between open and closed positions. A modulating package accepts a variable command such as 4-20 mA or 0-10 V to position the ball valve proportionally for process control.

Can an electric ball valve use customer-specified actuator brands?

A customer may specify an existing or preferred actuator model. Jinkon can review the torque, mounting interface, voltage, control and feedback requirements to confirm a compatible valve-actuator package before quotation.

Electric Actuated Ball Valve Selection Guide | On-Off & Modulating

An electric actuated ball valve should be selected as a complete valve-and-actuator package. Valve size alone does not establish the required torque, control function or mounting compatibility. The RFQ should state the operating medium, pressure and temperature together with the required electrical controls.

Project review: send the valve data sheet, drawing or existing actuator nameplate. Include the required voltage, signal, feedback and fail action so the mechanical and control interface can be checked before quotation.

1. Define the ball valve and process duty

Valve construction

State one-piece, two-piece or three-piece construction; full or reduced port; connection type; body and seat materials.

Operating condition

Provide medium, solids content, pressure, temperature, operating frequency and any corrosive, hazardous or outdoor environment.

Required function

Identify simple open/close isolation or modulating/regulating duty. Specify the desired action after loss of supply if applicable.

2. Match actuator torque and ISO 5211 mounting

For a quarter-turn ball valve, selection should account for break torque, running torque and seating torque at the actual differential pressure and temperature. Confirm the stem and ISO 5211 mounting interface, available clearance, manual override and the required duty cycle. An oversized or undersized actuator can affect operating life and shutoff performance.

3. Select the control package

Requirement	Typical specification input
On-off / open-close	Supply voltage, open/close command method, operating time, limit switches and manual override.
Modulating / regulating	4–20 mA, 0–10 V or project protocol; position accuracy, feedback and duty cycle.
Monitoring	Position feedback, open/close indication, torque alarm, local controls and cable entry requirements.
Environment	Ingress protection, ambient temperature, corrosion protection, hazardous-area requirements and certificates.

4. Customer-specified actuator models

For projects that specify Rotork, AUMA, SAMSON or another existing actuator model, share the nameplate, valve torque, interface, supply voltage, command and feedback requirement. Jinkon can review compatibility and provide or replace a valve-actuator package subject to engineering confirmation and availability.
