PFC PTF
1-1/16" (09) 5/32" OD
1-1/2" (17) 1-1/2" (098/196) 5/32" OD
2" (31) 2" (247/494) 1/4" OD
Air line connections are described in the illustrations below. Instructions follow. Also
consult the Appendix for air and electrical connections to PFCN, PFC, and PT.
• Connect the 70 -80 psi supply air to the center port of the valve manifold.
• Connect the valve manifold retract port (the port directly to the left of the
center port when the manifold is facing you) to the rod end of the cylinder.
o
For PTF rotary actuators, connect this to the port on Body “A” for
single rack models (left side when the PTF shaft is facing toward you),
or connect to bodies “A” and “D” for double rack models (lower left
and upper right when the PTF shaft is facing toward you).
• Connect the extend port (the port directly to the right of the center port when
the manifold is facing you) to the cap end of the PFC cylinder.
o
For PTF rotary actuators, connect this to the port on Body “B” for
single rack models (right side when the shaft is facing toward you), or
connect to bodies “B” and “C” for double rack models (upper left and
lower right when the shaft is facing toward you).
Do not turn the air supply on at this time.
