2.0 THRUST RATINGS
The
basic
thrust
pneumatic piston is equal to the area
of the piston times the supply
pressure.
The
pressure for both the TZID-C and the
AV1 is 20 psi.
The maximum supply pressure for
the TZID-C is 90 psi and 125 psi for
the AV positioner.
The area of the piston is A = πD
Subtract
approximately
friction losses and because the rod
side of the piston has less area. An
example is shown for an 80 psi air
supply:
