PRODUCT 
BHH Helical Hydraulic Quarter-Turn Actuator 
For over 50 years, Bettis has combined its ingenuity with high quality standards, continuously pioneering valve actuator technology. Beginning with the Robotarm scotch-yoke concept, Bettis innovative records has become today's standards for valve control in every part of the world.

Bettis introduces the latest valve automation advancement…the BHH helical hydraulic quarter-turn actuator.

The BHH and BHHF is a complete line of hydraulic double-acting and spring-return actuators. Compact and concentric, the proven design provides space savings and reliability.  Using the multiple helical splines engagement with reciprocal splines on the piston, the high torque output is constant throughout the 90 degree rotations, converting hydraulic energy into rotation, with the torque output proportional to the supply pressure.

The BHH and BHHF can be operated in the most severe conditions, from high vibrations to severe environment locations while providing a compact and reliable valve automation solution.

Easily adapted to all types of quarter-turn valves, dampers or louvers, the mounting positions are numerous, with available controls block options for direct mount modular control functions.

Typical Applications

  • Automation of ball, butterfly and plug valves
  • Automation of louvers and dampers
  • Automation of any quarter-turn mechanism
