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.
