New Rack & Pinion, Double Acting & Spring Return Pneumatic Actuators, Size O6 to 26



Ste. Genevieve MO--June 15, 2004--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 90° 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.

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 -40°F (-40°C) to +200°F (+95°C). 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.

The Series 100 actuators feature a one-piece pinion machined from hardened alloy steel and zinc-plated for corrosion resistance. Permanently lubricated acetal bearings support the pinion at both top and bottom. The die-cast aluminum pistons travel on lubricated acetal piston guides and rings that work in
conjunction with the pinion bearings to absorb operator side thrust and reduce the coefficient of friction. This results in extended service life and more efficient torque output. For increased corrosion protection, the extruded aluminum body is
anodized and the die cast end caps are polyester coated.

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