4105 ACTUATOR POSITIONER

DESCRIPTION

The 4105 Actuator Positioner is used in conjunction with pressure control heads to provide fast, accurate positioning of low-force mechanisms.

Input pressure acts against a piston, “U” cup and a spring, producing lever position output corresponding to input pressure.

The piston, “U” cup and large bearing surfaces for the rod and all lever pins assure low friction for fast, accurate response and long life.
