Electric Actuated Valves

Electric Ball Valves

High-performance quarter-turn ball valves (DN15–DN300) available in 2-way, 3-way, and V-port configurations, providing bubble-tight Class VI shut-off and high-pressure fluid isolation.

Electric Butterfly Valves

Cost-effective, compact quarter-turn valves (DN40–DN1200) in wafer, lug, and flanged body styles, engineered for high-volume flow control in water treatment, HVAC, and industrial utilities.

Electric Gate Valves

Heavy-duty multi-turn motorized gate valves designed for straight-through, full-bore flow with minimal pressure drop, ideal for high-pressure steam, oil pipelines, and municipal mains.

Electric Globe Valves

High-precision linear modulating control valves built for accurate throttling of steam, thermal oil, and feed water under severe high-temperature and high-pressure conditions.

Electric Knife Gate Valves

Rugged self-cleaning beveled knife gate valves engineered to cut through thick slurries, wood pulp, fly ash, mining tailings, and solid-laden wastewater without jamming.

Explosion-Proof Electric Actuated Valves

ATEX and IECEx certified explosion-proof (Ex d IIB/IIC T4/T6) motorized valves, guaranteeing spark-free, fail-safe operation in volatile petrochemical, refinery, and mining environments.

Miniature Electric Valves

Compact, low-power motorized micro-valves (DN15–DN25, 12V/24V DC or 220V AC) tailored for space-constrained OEM equipment, automated water filtration skids, and fan-coil units.

Valve Type Selection

Select the optimal valve pattern (Ball, Butterfly, Gate, Globe, or Knife Gate) based on your process duty: quick shut-off, high-volume flow, heavy slurry cutting, or precision linear throttling.

Connection Type & Bore Size

Define your nominal pipe diameter (DN15–DN1200 / 1/2"–48") and piping standard: Flanged (ANSI / DIN / JIS), Wafer, Lug, Female Thread (NPT / BSPT), or Grooved ends.

Body & Sealing Materials

Specify valve body construction (WCB Cast Steel, SS304, SS316, Cast/Ductile Iron, UPVC) and seat materials (PTFE, EPDM, Viton, or Hard Metal-to-Metal) compatible with your media.

Operating Temperature

Provide working temperature ranges (-40°C to +450°C) to ensure reliable seal endurance and determine whether thermal extension brackets or radiator fins are required.

Working Pressure & Torque Margin

Specify pipeline pressure ratings (PN10–PN160 / Class 150–900). Our engineers verify differential pressure and apply a 30%–50% actuator torque safety factor to prevent stalling.

Actuator Supply Voltage

Select power supply specifications matching your site control cabinet: DC12V, DC24V, AC24V, AC110V, AC220V, or 3-Phase AC380V/415V.

Control Method & Protocol

Choose operational logic: simple On/Off isolation, intelligent modulating (4-20mA / 0-10V analog signals), battery fail-safe emergency return, or Modbus RTU / Profibus digital DCS bus.

High-Precision Flow Modulation

Equipped with intelligent digital positioner cards supporting 4-20mA, 0-10V, and Modbus/Profibus signals. High positioning resolution and minimal deadband eliminate pipeline hunting, ensuring smooth, precise throttling across modulating duties.

Industrial All-Weather Enclosure (IP67 / IP68)

Die-cast aluminum alloy housing with multi-layer epoxy powder coating offers exceptional corrosion resistance. Built-in anti-condensation space heaters protect internal electronics against coastal humidity, extreme cold, and outdoor washdowns.

ISO 5211 Standardized Direct Mounting

Standardized ISO 5211 top mounting pads and dual-square drive shafts enable direct bracketless valve assembly. This rigid, direct-mount structure eliminates mechanical hysteresis, reduces torque transmission loss, and simplifies future maintenance.

Emergency Manual Override & Failsafe Return

Every unit features a declutchable handwheel or hex-drive socket for safe manual intervention during electrical power failures. Optional internal battery backup packs or supercapacitors automatically drive the valve to a safe open or closed position upon loss of power.

100% Pressure Testing & Zero-Leakage Sealing

From bubble-tight Class VI soft seats (PTFE/EPDM) to Stellite hard-faced metal-to-metal seals, every valve assembly undergoes 100% hydrostatic shell and seat pressure testing in accordance with API 598 / ISO 5208 before shipment.

Heavy-Duty Gear Train & Overload Protection

Precision-machined high-strength alloy worm gears and bronze gears ensure high torque output, low noise, and minimal backlash. Built-in thermal protection switches prevent motor burnouts, guaranteeing a long service life exceeding 50,000 operating cycles.
