Electric Actuated Valve

Electric Actuated Valve Manufacturer in USA 

Electric actuated valve with quarter turn, multi turn, and linear actuator packages for on/off and modulating duty are manufactured by SVR Global. These valves comply with API 598 standard and have ISO 5211 flange mountings. The enclosures of these valves are NEMA 4X and ATEX/IECEx certified, having control choices of 4-20mA, Modbus, and HART. These valves cater to Oil & Gas, Power Generation, and petrochemicals across US.

What is an Electric Actuated Valve?

Electric actuator valves are made up of a valve body together with an electric actuator which operates the valve automatically. The actuator acts upon a signal generated by the control system to convert electrical energy to rotary motion for quarter turn valves and multi-turn for gate type valves or linear for globe type valves.

Control Signal and Communication Protocols

Electric actuators accept a range of control inputs depending on the plant's control architecture:

• 4–20mA analog: standard current loop signal for modulating position control

• Discrete on/off / relay contact: simple open-close-stop commands for isolation duty

• Modbus (RTU/TCP): digital protocol for integrating position feedback and diagnostics into a control system

• HART: overlays digital data onto a 4-20mA signal for diagnostics without adding wiring

• Profibus / Foundation Fieldbus: digital bus protocols used in larger process plants for integrated actuator networks

Specifying the correct protocol up front avoids a mismatch between the actuator and the plant's existing control system. This is one of the most common sourcing mistakes buyers run into.

Power Supply Options

Electric actuators are available across multiple voltage and current configurations:

• 24VDC / 24VAC - common in instrumentation and low-voltage control loops

• 120VAC single-phase - standard in general industrial and commercial installations

• 230/240VAC single-phase - common outside North America and in some US industrial settings

• 380-480VAC three-phase - used on larger actuators with higher torque/thrust output

Enclosure and Environmental Ratings

Actuators installed outdoors or in washdown, corrosive, or hazardous environments need an enclosure rating matched to that environment:

• NEMA 4 / 4X: weather-tight and corrosion resistant, suited to outdoor and washdown locations

• NEMA 7 / IECEx / ATEX: explosion proof ratings for hazardous locations where flammable gas or vapor may be present, such as oil and gas or chemical processing sites

• IP65 / IP67: international ingress protection ratings for dust and water resistance, referenced alongside or instead of NEMA ratings depending on the spec

Standards and Certifications

• IEC 60034 / NEMA MG1 - motor performance and construction standards referenced for the actuator's electric motor

• ISO 5211 - mounting interface standard ensuring the actuator bolts directly to the valve without custom brackets

• API 598 - hydrostatic and functional testing for the valve body itself, applied before actuator mounting

• ATEX / IECEx - hazardous location certification for actuators installed where explosive atmospheres may be present

Testing and Quality Control

• Functional stroke testing: every actuated valve cycle tested through full open close travel to confirm correct stroke time, torque/thrust output, and limit switch or position feedback accuracy before shipment

• Hydrostatic testing: the valve body tested per API 598 prior to actuator mounting, confirming body and seat integrity independent of the actuation package

• Material Test Reports (MTRs): heat traceable documentation for the valve body and trim materials

• Burn-in / duty cycle testing: for modulating duty actuators, extended cycling under load to confirm the actuator meets its rated duty cycle classification before it ships

Industries and Applications

• Oil and gas - remote isolation, sectionalizing, and automated skid packages

• Petrochemical and refining - utility isolation and automated process line control

• Power generation - modulating control of steam, feedwater, and combustion air/damper systems

• Water and wastewater - automated isolation and flow control across treatment and distribution systems

• Chemical processing - automated isolation and modulating control of corrosive or hazardous media lines
