LIMIT STOP PLATE DIMENSIONS
Description
These limit stop plates are used when precise control is required for both end of stroke positions.
It is possible to adjust 15° of both ends of the standard stroke.
Construction
The complete stop plate assembly may be added to the 90° P- series actuators.
The assembly is normally sandwiched between the actuator and mounting surface of the valve
or bracket. Bearing rings are used at both surfaces to provide a long life expectancy.
The unit is assembled with a drive adaptor which passes through the stop plate, into the square
actuator and provides the coupling between the two components.
This drive adaptor normally also accommodates the coupling of the valve stem.
Identification
"LS420" is added to the basic part number i.e. PD2500-LS420
