2.
Mounting holes (suffix = “M”)
. Threaded holes situated on the
bottom of the valve body. Refer to installation drawing (page 12) for
dimensions.
The mounting holes cannot be used in combination with the manual
override button.
3.
Position feedback sensor (suffix = “F”)
. The feedback sensor
provides secondary, independent confirmation of the plunger
position (more details on page 14). The feedback option is available
for:
a. 100P2NC 2-way normally closed valves
b. 100P3 3-way valves
c. 100PD dual tubing valves
4.
Factory-installed mounting flange (suffix = “L”)
. The mounting
flanges are available for all 100P pinch valve configurations. They will
be installed at a 90º angle to the tubing with the orientation to the
outside of the bulkhead.
This mounting flange can be purchased as a stand-alone item under
part number MU-100 (more details on page 16).
F. “Hit and Hold” voltage reduction
Within 100 ms of valve actuation, the voltage required to hold the
valve in position can be reduced. The voltage step-down results in
the dual benefits of power conservation and heat reduction. The
amount of the voltage reduction possible is 66% (i.e. 24 Vdc to 8 Vdc
or 12 Vdc to 4 Vdc) for all 100P pinch valves that do not incorporate
the “quiet” feature. This results in a power usage reduction of 89%,
resulting in a correspondingly large drop in heat generation.
For the 100P pinch valves with the “quiet” feature, voltage can be
reduced by 50% (i.e. 24 Vdc to 12 Vdc and 12 Vdc to 6 Vdc) after 100
ms for a power usage drop of 75%.
This voltage reduction can be accomplished using the Bio-Chem
Fluidics CoolCube™ hit-and-hold circuit (more details on page 14).
E. Available options, 100P series pinch valves
1.
“Quiet” operation (suffix = “Q”)
. The quiet option reduces the
valve noise level from about 72 dB (A) to less than 50 dB (A). The
quiet option is available for:
a. 100P2NC 2-way normally closed valves
b. 100P2NO 2-way normally open valves
The “quiet” option cannot be used on 100P3 3-way valves. The
noise level of the 3-way valves is inherently attenuated by tubing
dampening the motion in both directions.
