Designed for use on rising-stem globe control valves, the PL Series actuators (photo) provide up to 4,400 lb of force and up to 3.9 in. of travel. This increased up-and-down force, the company says, allows the use of globe valves for increased flow control in larger pipe diameters with higher close-off pressures compared to a corresponding butterfly valve with less flow control and lower close-off pressure. The force and travel of the PL Series actuators is said to be greater than competitive electric linear actuators. Key features of the PL Series actuators include: field-selectable travel stops, a customizable mounting system, precision proportional control, a manual override system and others. — Promation Engineering Inc., Brooksville, Fla.
