4207 DOUBLE-ACTING, SELF-CENTERING ACTUATOR

DESCRIPTION

The 4207 is a double-acting and spring-centered air actuator. The rod-lever configuration provides fourteen (14) different strokes which could be positioned into eight (8) different planes by rotating the rod end cap.

APPLICATIONS

• Used in conjunction with Kobelt pressure control head 2543, the 4207-A provides infinite positioning in two directions. It is best suited for accurate positioning and control of variable hydraulic pumps, and variable hydraulic valves or governors

• Used in conjunction with Kobelt control heads 3609, 2544 and 2545, the 4207-C is a most versatile 3-position cylinder, providing fourteen (14) different strokes
