EL-O-MATIC ACTUATOR WITH ONE WAY LIMIT STOPS L1/LF
Description
Actuators with one way adjustable limit stops are used where the maximum opening (or closing)
position of the valve needs to be reduced. For instance to adjust the maximum capacity of a
remote operated valve.
Also actuators with 180° rotation are available with these stops.
Operation
Stop screws are fitted to both endcaps and the screw length is such that adjustment is possible
through the specified rotation of the actuator.
The modified endcap is machined for -0.5° to +93° rotation for all P-series models.
Identification
“L1” is added to the basic part number i.e. PD2500-L1
