New rack and pinion, double acting actuators

Eight different models of rack and pinion, double acting and spring return pneumatic actuators provide output torques from 300 lb inches up through 29,000 lb inches, for the Ultraflo butterfly valves

Ultraflo has announced the 100 Series actuator product line.

The 100 Series is a pneumatically driven rack and pinion actuator available in double acting and spring return designs, both providing a 90deg rotation.

The 100 Series features a compact, economical package incorporating many standard features only offered as options on many competitive models.

Eight different models provide output torques at 80 psi from 300 lb inches up through 29,000 lb inches, in size 06 to 26.

The 100 Series offers mounting to the complete line of Ultraflo butterfly valves, as well as NAMUR standards for mounting of Ultraflo accessories.

The 100 Series actuators are designed primarily for pneumatic actuation up to a maximum pressure of 140 psig (10 Bar) and for temperatures ranging from -40degF (-40C) to +200degF (+95C).

These actuators are also available for operation with alternative media such as hydraulic oil and water.

Special features include pre-loaded, contained cartridge spring packs in the Spring Return units.

The spring packs offer enhanced safety, ease of maintenance and reduced space requirements.

Conversion between Spring Return and Double Acting units is accomplished simply by the insertion or removal of the spring packs.

All other components are identical.

The pre-loaded spring packs eliminate the need to control spring tension by the end caps and retaining bolts.

The Ultraflo 100 Series pneumatic actuator is a fully enclosed and self-contained unit designed for ease of use and maintenance.

Integral porting eliminates the need for costly, cumbersome and easily damaged external tubing.

Integral travel stops are housed in each end cap to precisely control the degree of travel operation.

Double acting units have a constant output torque throughout travel from start to end, clockwise or counter-clockwise rotation.
