Electro-Hydraulic Valve Actuators
Electro-Hydraulic Actuators are driven by the hydraulic pressure generated from an electric motor, which is then delivered to the hydraulic cylinder to control the valve.
Compact and All-in-One
Safe and Reliable
RPMTECH actuators are equipped with hydraulic pressure generators, a high tech controller, and a manual hand pump based on patented technology. The compact, all-in-one design and the modular installation capabilities makes the actuators versatile and easy to conduct maintenance.
RPMTECH actuators support a variety of communication platforms to best fit the needs of the end user. The user can access virtually all settings and advanced control modes via the LCD display. The self-diagnosis feature allows for simple maintenance and maximum efficiency.
RPMTECH actuators are engineered (both software and hardware) to maximize the safety of the user and enhance the reliability of the product. The manual hand pump is engineered based on patented technology and adds more reliability especially during a power loss or emergency. Also, Modular Installation allows for the actuator to be installed at a safe and accessible location.
