Designed for compactness and reliability >

Hydraulic double-acting and spring-return helical quarter-turn actuator.Compact and concentric, the proven design pro-vides space savings and reliability.Using the multiple helical spline engagement with reciprocal splines on the piston, the high torque output is constant throughout the 90 degree rota- tions. Converts hydraulic energy into rotation, with 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.Easily adapted to all types of quarter-turn valves, dampers or louvers.

Hand pumps can be installed on all standard actuators BHH, BHHF, BL, BLF. They are available for use with single acting or double acting configurations. Depending on the actuator size, control type and valve loca-tion, the hand pumps can be used for emergency operation and standalone operation without other remote facilities. Direct Mounted Hand PumpPortable Hand Pump > The Bettis Valve Position Indicators (VPI) program is designed to locally or remotely indicate the position of hydraulically-op- erated actuators with determined displacement. It continu- ously indicates valve position by measuring...

The Bettis control block system is designed for mounting on, or close to, the BHH, BHHF, BL and BLF actuators. For use with any of the actuators for conventional, submerged, or hazardous location service, the actuator can be connected to the pilot line by means of a B-block.
