ABOUT US
AOITEC
Electric Valve Actuator Manufacturer
AOITEC designs and manufactures electric valve actuators and electric valves, backed by R&D and production experience since 1996 at AOITEC (GD) Co., Ltd. Our quarter-turn range covers the Ulli on-off series (20–6000 Nm) and the Digicon modulating series (50–6000 Nm), plus Highspd® high-speed, brushless DC (BLDC), SuperCap failsafe and explosion-proof actuators. Ulli and Digicon actuators are IP68-rated, CE-certified and mount directly to ISO 5211 valve flanges without brackets. AOITEC International in Singapore manages global sales and technical support for customers in more than 30 countries.
OUR STORY
Electric Valve Actuators
Choose by control type: Ulli for on-off service, Digicon for modulating control. For fast stroking, frequent cycling, fail-safe return on power loss or hazardous areas, see our Highspd®, BLDC, SuperCap and explosion-proof series.
Why Choose Us
HIGH RELIABILITY & LONG SERVICE LIFE
Built for customers who prioritize reliability and long-term cost effectiveness. Durable internal components, stable performance and strict quality control mean dependable operation, reduced maintenance and lower lifetime operating costs.
S1 100% DUTY CYCLE WITH BRUSHLESS DC TECHNOLOGY
A brushless DC motor supports S1 100% duty for uninterrupted, high-frequency operation. Built-in stall protection removes the risk of overheating, with faster response, longer service life and zero brush wear. Wide voltage input AC 20–40 V / AC 100–260 V.
TRULY BRACKET-FREE, ULTRA-COMPACT DESIGN
Unlike most direct-mount actuators, AOITEC fully eliminates internal brackets. ISO 5211 mounting allows direct valve installation, saving space and weight, ideal for tight or hard-to-reach spaces.
SUPERCAPACITOR FAILSAFE TECHNOLOGY
A more compact and lightweight alternative to spring return, without the overcharging and over-discharging risks of battery-based failsafe. On power loss, stored supercapacitor energy drives the valve to its preset fail-safe position. Wide voltage input AC 20–40 V / AC 100–260 V.
ADVANCED & FLEXIBLE ENGINEERING
Application-driven engineering supports custom voltage, control logic, speed, mounting and functions such as brushless DC, failsafe, high speed and explosion proof. Our in-house R&D team works closely with customers to adapt solutions for different industries and project specifications.
FAST LEAD TIME
Efficient production planning keeps lead times short, even for customised solutions and project-specific requirements. Standard lead time can be as short as 3 working days.
COMPETITIVE GLOBAL PRICING
High performance and functionality with more competitive pricing through optimised designs, backed by a resilient global supply chain.
RELIABLE SUPPORT & WARRANTY
Responsive technical support and a reliable 2-year warranty mean smoother communication and faster troubleshooting. Our team works closely with customers throughout the project cycle, with dependable after-sales support.
