Description
A range of compact linear actuators having 5 diaphragm sizes for matching the requirements of
different valves at various differential pressures. Each actuator is fitted with a stroke indicator
and incorporates a semi-rolling diaphragm which gives good linearity over the operating
stroke.These actuators are designed to operate with two port LE valves as detailed below.
Available types
Spring extend spindle, multi spring, yoke mounted actuators 3200, 3300, 3400, 3500, and 3600 Series.
