Camflex Rotary Valve Mounting
Installing the FVP110 on the
1. Turn the A/M selector switch clockwise to
M
(Figure 26).

2. Vary the pneumatic pressure output to the valve actuator by changing the regulator
output pressure by more than 70 kPa (approximately), regardless of the input signal
of the FVP110. For an FVP110 equipped with pressure gauges, you can read the
output pressure to the actuator.
When using the Double Acting Type, the pneumatic pressure can only be varied
from
OUT1
to the valve actuator. The pressure is always 0% from
OUT2
to the
valve actuator. The valve position is not always in accord with the regulator
pressure.
3. Turn the A/M selector switch counterclockwise until the stopper pin touches the side
of the FVP110’s casing to ensure the switch position changes to
A
.
Camflex Rotary Valve Mounting
This section describes the procedure for mounting the FVP on rotary control valves,
using GE Masoneilan rotary valves as an example. Refer to Figure 27 on page 44 and
Figure 28 on page 45 for details.

has four sides, two square and two rectangular.
One square side has a large hole in the center with four smaller holes above, below, left
and right of the center hole; this side mounts to the actuator.
The other square side has a large hole that is a little bit off center and two rows of two
smaller holes above and below the large hole; this side mounts to the FVP.
