Valve Actuators for Industrial Automation

Quarter-Turn Electric Actuators

Compact 90° rotation (18 Nm to 4,000 Nm) for ball, butterfly, and plug valves; available in On/Off or 4-20mA continuous modulating duty.

Multi-Turn Electric Actuators

High-thrust linear stem drives (up to 300,000 Nm thrust) with multi-rotation encoders, built for rising-stem gate valves, globe valves, and water penstocks.

IP68 Water-Proof Submersible Actuators

Certified for continuous underwater immersion (10 meters depth for 72 hours), ideal for underground valve pits and flood-prone chambers.

IP67 Explosion-Proof Electric Actuators

Heavy-duty flameproof enclosures certified to ATEX and IECEx (Ex d IIB/IIC T4/T6), delivering spark-free safety in volatile oil, gas, and refining zones.

AT Series Rack and Pinion Actuators

Compact, symmetrical twin-piston design providing linear, balanced torque output. The standard, cost-effective choice for small-to-medium quarter-turn valves.

AW Series Scotch Yoke Actuators

Heavy-duty U-shaped torque curve design delivering massive break-away torque (up to 50,000+ Nm). Engineered specifically for high-pressure, large-bore ball and butterfly valves.

Motion & Stroke Type

Define your valve movement: Quarter-Turn (90°) for ball, butterfly, and plug valves, or Multi-Turn Linear for rising-stem gate, globe, and weir valves.

Required Operating Torque & Safety Factor

Determine the valve’s maximum break-away and dynamic torque under peak differential pressure. Always apply a 30% (clean liquid) to 50% (slurry/viscous media) engineering safety margin.

Driving Power Source

Select your plant utility: Electrical supply (24VDC, 110VAC, 220VAC, or 3-Phase 380V/415V) or Clean shop compressed air (4 to 7 bar / 60–100 psi).

Fail-Safe Emergency Requirement

Choose your failure state: standard Fail-in-Place, mechanical Spring-Return Fail-Safe (Pneumatic: Fail-Close or Fail-Open), or internal Battery-Backup / Supercapacitor (Electric).

ISO 5211 Flange & Drive Shaft Dimensions

Match top mounting flange standards (F03, F05, F07, F10, F12 up to F30) and specify drive shaft dimensions: double-square, keyed bore, or parallel flat drive.

Control Mode & Signal Integration

Select operational format: simple On/Off dry contact switching, analog proportional modulation (4-20mA / 0-10V), or digital industrial communication bus (Modbus RTU / Profibus-DP).

Environmental & Hazardous Ingress Rating

Specify site protection standards: standard weatherproof IP67, continuous submersible IP68, or ATEX / IECEx Ex d explosion-proof for hazardous gas and dust atmospheres.

Comprehensive Rotary & Multi-Turn Motion (Electric Intelligence)

From precise 90° quarter-turn rotation for ball and butterfly valves to high-thrust multi-turn linear stem drives for heavy gate and globe valves. Built-in electronic torque switches and position sensors dynamically protect the valve stem from bending or shearing under mechanical jam conditions.

Dual Pneumatic Drive Technologies (AT Rack-Pinion & AW Scotch-Yoke)

We offer compact AT rack-and-pinion actuators for rapid, balanced linear torque, alongside heavy-duty AW scotch-yoke actuators delivering parabolic torque output up to 50,000+ Nm. The scotch-yoke design peaks precisely at the opening and closing points, conquering high valve break-away seat friction while reducing air consumption by 30%.

Severe Environment Protection (True IP68 Submersible & ATEX Ex d)

Engineered for the harshest field conditions. Our electric actuators feature certified IP68 continuous submersion ratings (tested at 10 meters depth for 72 hours) for flood-prone underground vaults, as well as heavy flameproof enclosures certified to ATEX and IECEx Ex d IIB/IIC T4/T6 with built-in anti-condensation heaters for explosive chemical zones.

Non-Intrusive Smart Calibration & Digital Bus Telemetry (Electric)

Equipped with digital microprocessor positioner cards supporting high-resolution 4-20mA / 0-10V proportional modulation and Modbus RTU / Profibus-DP bus communication. A local LCD screen and non-intrusive infrared remote control allow operators to calibrate stroke limits and torque settings on-site without opening the electrical housing in rain or hazardous gas.

Universal ISO 5211 Direct Mounting & Custom Drive Bushings

Manufactured in strict accordance with ISO 5211 top flange dimensions (F03 through F30) and NAMUR VDI/VDE 3845 accessory interfaces. We provide direct bracketless mounting and factory-machined custom drive sleeve bushings (double-square, keyed bore, or parallel flat) to guarantee a zero-backlash drop-in retrofit on any valve brand.

Dual Fail-Safe Technologies & 100% Full-Load Testing

True emergency protection: choose mechanical pre-stressed spring-return cartridges (pneumatic) or internal rechargeable battery/supercapacitor packs (electric) for automated fail-close or fail-open safety upon utility loss. Every unit undergoes 100% dynamic torque testing and electrical insulation / pneumatic pressure decay testing before shipping.
