LP LINEAR PISTON ACTUATORS INSTRUCTION MANUAL

3.0 NOMENCLATURE
“Simple Cylinder” type Linear pneumatic piston actuators are supplied with either type AV conventional
or type TZID intelligent positioners mounted on the cylinder. Cylinders are supplied with a threaded clevis
on the rod end and a standard MP pivot on the base. Base mounting pivots may be ordered as an
accessory.
The cylinders can be supplied with either Buna-N nitrile rubber seals suitable for 200
o
F (93
o
C) operation
or Viton seals suitable for 300
o
F (148
o
C) 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 (121
o
C). All other positioners have a 185
o
F (85
o
C) maximum ambient. Buna-N seals are
recommended unless temperatures > 200
o
F (93
o
C) dictate Viton.
The TZIDC-200 is for Explosion Proof application Class I Div 1 Gr. C-G. Refer to the AV or TZIDC
positioner specifications for positioner details and specifications.
The maximum supply pressure with type TZIDC positioners is 90 psi. The maximum supply pressure with
type AV positioners is 125 psi.
Please refer to the individual Instruction Books for the AV and the TZIDC
positioners for details on the two types of positioners (Refer to table of Reference
Documentation shown below).
