PN1000 Series Spring Extend Pneumatic Actuators Description

PN1000 Series Spring Extend Pneumatic Actuators
(for LE/LEA and KE/KEA Valves 2-1/2" to 4")
Description
A range of single spring linear actuators having 2 diaphragm
sizes for matching the requirements of different valves at
various differential pressures. Each actuator is fitted with a
combined mechanical stroke indicator and anti-rotation guard.
The actuators are designed for easy conversion from spring
extend to spring retract, and vice versa, without the need for
special tools.
Available types
Spring extend spindle actuators:
PN1500 and PN1600 series.

PN1000 Series Spring Extend Pneumatic Actuators
Differential pressures for LE/LEA and KE/KEA series valves and PN1000 series actuators (spring extend)
Note: The differential pressures stated in the tables below are limited by the maximum operating pressures of the selected control valve.
In certain circumstances with a reduced Cv value, or where reduced valve stroke is acceptable, it may be possible to increase the maximum
differential pressure above that shown in the table by special setting of the actuator. Please consult Spirax Sarco.
