LP LINEAR PISTON ACTUATORS INSTRUCTION MANUAL

3.0 MODEL NUMBER DETAILS
“Simple Cylinder” type Linear pneumatic piston actuators are supplied with either type AV conventional
or type TZID intellegent positioners mounted on the cylinder. Cylinders are supplied with a threaded
clevis on the rod end and a standard MP pivot on the base.
The cylinders can be supplied with either Buna-N nitrile rubber seals suitable for 200
o
F operation or Viton
seals suitable for 300
o
F operation. The Buna-N seals have a lower breakaway pressure, offering
smoother modulating control. High temperature Viton seals are inherently higher friction and tend to stick
and breakaway, causing somewhat jerky motion. The operating temperature for the AV15 & AV16 is
250
o
F. All other positioners have a 185
o
F maximum ambient. Buna-N seals are recommended unless
temperatures > 200
o
F dictate Viton.
Please refer to the individual Instruction Books for the AV and the TZID-C for
details on the two types of Positioners.
