Valve actuator HyRAV® Flex
powerful, compact and safe
Advantages
at a glance
- small dimensions
- slim and compact style
- durable against vibrations
- easy installation and adjustment to each valve
- robust against extreme environmental conditions
- concentric design protects the valve and the spindle
- no lubrication required, because all moving parts of the actuator are permanent in the oil bath
- ISO5211 or ANSI flange
- ATEX and SIL
Reliable
even under extreme conditions
The HyRAV® Flex rotary actuators form a complete series of dual-action or spring-return rotaty units which work according to the helical gear principle.
The compact and concentric fitting on the valve has proven to be effective in practice and the unit is both space-saving and reliable. This series can be deployed in the most difficult conditions, from heavy vibrations to adverse ambient conditions, and offer a powerful and safe solution for valve control.
Due to the spacious, hollow shaft design and customisable flanges, the series can be adapted to each valve type.
