TriVAX® – Electrohydraulic valve actuator
TriVAX valve actuators have a piping-free design with a closed and precharged hydraulic system which makes it unique. Thereby it provides a compact design, lowest maintenance costs and a quite simple and quick installation.
TriVAX actuators are certified for installation in potentially explosive atmospheres.
Applications
- Oil & Gas Storage
- Pipeline
- Heat Storage
- Fail Safe
What tasks are performed with TriVAX technology?
Valve actuators with closed hydraulic systems suitable to operate linear and quarter turn valves in On-Off or positioning mode with SIL certified safety function.
Why TriVAX technology?
- In TriVAX influences of the environment on the hydraulic fluid are eliminated which leads to long maintenance periods, safe fail-safe functionality and reliable operation.
- The closed and precharged hydraulic system allows the installation of actuator in any position.
- All settings can be done without opening housings or hatches.
- TriVAX allows flexible diagnostic options during the process.
- TriVAX is certified for the complete actuator to be used in all potentially explosive atmospheres.

TriVAX Basic is a manual operated actuator with controlled spring return function. The spring return function is possible to be released by solenoid- and/or pilot valves. The closed and precharged hydraulic system allows to install the actuator in each mounting position and leads to long maintenance periods, which safe costs and time. TriVAX Basic is available also with linear motion.
