Help us identify the right solution
Configure a complete assembly

Start by configuring your valve

Select the valve and enter its process conditions first. If actuation is required, the RFQ will continue to the compatible actuator and retain the valve data automatically.

FAQs

EFJ4C is intended for ball valves and butterfly valves requiring quarter-turn rotary movement. Final compatibility depends on valve torque, mounting interface, output drive and service conditions.
Yes. EFJ4C is intended for ball and butterfly valves. EFSVALVES verifies the valve data, mounting interface, operating torque and engineering margin before selection.
Selection is based on the valve operating and breakaway torque, required safety factor, operating frequency, power supply, environmental conditions and mechanical interface. For an EFSVALVES valve assembly, these checks are completed internally by our engineering team.
The range includes six actuator sizes covering nominal torque requirements from 20 to 300 Nm. The actuator is not selected from nominal valve size alone; the actual valve torque and service must be reviewed.

ABOUT EFJ4C

The EFJ4C electric quarter-turn actuator is engineered to automate industrial ball valves and butterfly valves operating through a nominal 90-degree movement. Six actuator sizes cover torque requirements from 20 to 300 Nm, supporting automated isolation, flow control and process-valve operation across water treatment, desalination, chemical processing, food and beverage, pharmaceutical and general liquid-service applications.

A brushless electric motor, electronic torque limiter and standard voltage-free open and closed position contacts support dependable integration into industrial control systems. The IP67 enclosure incorporates visual position indication, a declutchable manual override and thermostatically controlled internal heating to help reduce condensation.

EFJ4C can be configured for straightforward On/Off operation or DPS digital positioning using 4-20 mA, 0-20 mA, 0-10 V or 1-10 V signals. Optional BSR battery backup can move the valve to a predefined open or closed safety position following loss of external power. Bluetooth communication and Modbus integration are also available for projects requiring local configuration, diagnostics or networked control.

When EFJ4C is supplied with an EFSVALVES valve, our engineering team verifies the operating and breakaway torque, safety margin, mounting interface, output drive and actuator size. Customers therefore configure the valve and the required electrical functionality without having to calculate mechanical selection data. EFJ4C may also be requested separately for an existing third-party valve, subject to review of the valve datasheet and torque information.

Frequently Asked Questions

The range includes six actuator sizes covering nominal torque requirements from 20 to 300 Nm. The actuator is not selected from nominal valve size alone; the actual valve torque and service must be reviewed.
Yes. Standard On/Off operation is available, while the optional DPS digital positioner supports 4-20 mA, 0-20 mA, 0-10 V and 1-10 V control signals.
Without the BSR option, the actuator remains in its existing position. When the optional BSR battery system is specified, it can move the valve to a predefined normally open or normally closed safety position.
EFJ4C is available in multi-voltage versions accepting 24-240 VDC/VAC and dedicated versions for 12 VDC/VAC. The required supply must be defined in the RFQ.
Yes. Bluetooth can support local setup and diagnostics, while Modbus can be specified for networked control. The communication architecture should be confirmed during project review.
Yes. EFSVALVES can supply the selected valve, actuator, mounting arrangement and engineering review as one coordinated assembly, with the actuator quantity linked to the valve quantity in the RFQ.
Yes. For an existing or third-party valve, provide its manufacturer, model, datasheet and available torque and mounting information. EFSVALVES will review compatibility before proposing the actuator configuration.
It can automate compatible valves used in these facilities, subject to environmental and project requirements. The actuator itself should not be interpreted as providing a hygienic-process or hazardous-area certification unless expressly documented for the selected configuration.
An electric quarter-turn actuator converts electrical power into a rotary movement of approximately 90 degrees. It is commonly used to automate quarter-turn valves such as ball valves and butterfly valves, providing remote On/Off or positioning control depending on the selected actuator configuration.
A quarter-turn actuator typically rotates approximately 90 degrees and is used with valves such as ball and butterfly valves. A multi-turn actuator provides several complete rotations and is used where the valve mechanism requires multiple turns to move between positions. The correct actuator type therefore depends on the mechanical movement required by the valve.
An electric actuator can be particularly suitable where electrical power is available but compressed instrument air is not, or where electrical positioning, communication or local electronic configuration is preferred. A pneumatic actuator may be more appropriate where fast operation, simple spring-return fail-safe action or an existing instrument-air network is available. The choice depends on available utilities, required fail position, control philosophy, operating frequency and installation conditions.
The optional BSR battery system allows EFJ4C to move the valve to a predefined open or closed safety position if external electrical power is lost. Without the BSR option, the actuator remains in its existing position following loss of external power.
EFJ4C has an IP67 enclosure, providing protection against dust ingress and temporary water immersion under the conditions defined by the IP classification. The complete installation should still be checked against the actual environmental conditions, including outdoor exposure, washdown, corrosion or other project-specific requirements.
It can be considered where its documented IP67 enclosure and environmental characteristics are compatible with the installation. For severe outdoor, marine, corrosive or washdown environments, the complete actuator and installation conditions should be reviewed before final selection.
Yes. EFJ4C provides voltage-free open and closed position contacts for integration into industrial control systems. Optional DPS positioning, Bluetooth and Modbus communication are also available depending on the selected configuration and required control architecture.
Yes. EFJ4C can be supplied as part of a complete automated valve assembly for EPC and project-managed applications. The project scope can include the selected valve, actuator, mounting arrangement and engineering review, with torque, breakaway torque, safety margin, mounting interface, output drive, power supply and control requirements checked as part of the actuator selection. Any project-specific documentation, communication or control requirements should be identified during the RFQ stage.
