Linear Piston Actuator Assemblies
The LP series of damper drives provide a linear
actuation solution that is ideally suited for
applications to control the position of air
dampers or louvers on furnaces, boilers, and air
distribution systems. They are also used on
Burner Tilts and Overfire air dampers. They are
suitable for Windbox damper control in NOx
reduction control systems.
The conventional assembly, which uses the AV
Positioner series, offers a high-temperature
option up to 250
o
F. In comparison our digital
TZIDC solution allows for operation up to 185
o
F.
LP sizes range from a 2.5” diameter cylinder
with a 5” stroke (2.5”x 5”) up to a 10”x 16”
diameter cylinder. The most common sizes,
2.5”x 5” and 4”x 4,” are readily available.
Operation with TZIDC Smart Positioners offers
digital communication, self-calibration,
diagnostics and performance monitoring
functions.
TZIDC Digital Features
• Microprocessor-based
The “AutoStroke” feature calibrates and tunes
the LP assembly automatically.
