1.0 SPECIFICATIONS / FEATURES
LP linear piston actuators are used to control the
position of air dampers or louvers on furnaces,
boilers, and air distribution systems. They are
also used on burner and SOFA Tilts. They are
suitable for Windbox damper control in NOx
reduction control systems.
Operation with TZID-C Smart Positioners offers
digital communication, self-calibration,
diagnostics and monitoring functions. The
“AutoStroke” feature calibrates and tunes itself
automatically.

position feedback.
Linear Piston Actuator Assemblies
The LP series of damper drives provide a linear
actuation solution that is ideally suited for
applications like Windbox-dampers. The
conventional assembly, which uses the AV
Positioner series, offers a high-temperature
option up to 25
o
F. In comparison, our digital
solution allows for operation up to 185
o
F, plus
the added features of digital control.
LP sizes range from a 2.5” diameter cylinder
with a 5” stroke (2.5”x 5”) up to a 12”x 14”
diameter cylinder. The most common sizes,
2.5”x 5” and 4”x 4,” are readily available.
