T Series Actuator Overview
The T-Series actuator demonstrates how we are committed to making life easier. An OEM of over the road bulk carriers was impressed by the capabilities of our Rack & Gear® actuators and they appreciated our ability to mount to numerous valves simply by selecting the proper adapters and mounting plate.
However, their application requires relatively frequent valve replacement (as well as the actuators they had been using) and their experience has been that small parts such as adapters are frequently lost during maintenance. Also, due to space issues they had developed a special short mounting for accessories that was not compatible with the typical international mounting standards.
In answer to their needs, we developed the T-Series which is based on the normal Q-Series Rack & Gear® design but which has unique multi-mounting pattern bodies and made to purpose shafts that allow direct fit to their existing valve with no bracketry or adapters. Also, accessory mounting geometries were modified to suit their existing designs.
Piston axis aligns with the pinion gear pitch circle diameter, eliminating the cantilever forces inherent in rack and pinion type actuators. Low friction rollers maintain correct engagement of the stainless steel gearing for absolutely exceptional cycle life.
The reduced friction enables outstanding throttling control as demonstrated in numerous 'typical diaphragm actuator' applications where corrosion or high vibration dictated a better solution.
Q Series
Offset cylinders align the piston axis with the pinion gear pitch circle diameter, eliminating the cantilever forces inherent in rack and pinion type actuators. Low friction rollers maintain correct engagement of the stainless steel gearing for absolutely exceptional cycle life.

F Series
A unique slotted body concept absorbs 100% of the yoke mechanism's side loading forces leaving the piston rod completely free of bending stresses while allowing termination of the rod at the yoke, and the addition of a weight and force balancing second force module diagonally offset from the first. The balanced weight makes lifting and handling of the actuators safer and easier, while reducing valve neck stress caused by unbalanced scotch yoke actuators. Internally, the balanced forces assure less friction loss and less wear as there is no net force applied to the shaft bushings.

L Series
Using captured springs and the linear components of our rotary, our L Series Actuators provide a safe, long lasting, low friction, stainless steel substitute for diaphragm types in a smaller package for resistance to corrosion and vibration.
XRCISER®
The standard QTRCO actuator uses a travel stop screw in the end cap to limit outward travel of the actuator piston, and therefore valve travel. In the XRCISER® configuration the pneumatically engaged tandem pistons become the outward travel stop. By confirming tandem piston pressure and position; spurious valve travel is prevented during the partial stroke cycle.
Accessories
A wide range of valve actuator accessories make your valve actuator more useful and versatile.
