Bronkhorst Mini CORI-FLOW - Manual (Page 9)

BRONKHORST CORI-TECH B.V.
1.1.4 Badger Meter Valves
For those special applications where the Bronkhorst valves do
not meet the specifications anymore we can use Badger Meter
valves as a good alternative.
Reasons for using an alternative valve could be requirements
for:
- Higher maximum pressure or delta-pressure
- Higher Kv-values
- Higher or lower temperatures
- Faster response time
- Metal sealed (e.g. for supercritical gases like CO2 or
ethylene)
Badger Meter offers a wide range and variety of valves. These
membrane valves are operated indirectly using an I/P-converter
with compressed air. The I/P-converter is connected to the controller output of the mini CORI-FLOW.
To be able to meet the quality and security standards Bronkhorst is used to, we will accept only those Badger
Meter valves which meet the “Bronkhorst Quality Norm”.
This norm includes certain predefined specifications to enable our production department to adjust, optimize
and test these valves if they were Bronkhorst valves.
Main items on this “Bronkhorst Quality Norm” are:
• Limit amount of models: RC200, ¼”, ½” and 1” types
• Special O-ring chambers in valve bodies for Swagelok RS adaptor types (no NPT)
• If no O-rings possible: adaptors welded to valve body
• Spindle seals: Kalrez compound 3035 (in stead of Teflon) for reduced emission
For operation interface:
• ABB TEIP11 I/P-converter: input signal 4-20 mA / output signal 0,2-1 bara
(or 0.4-2 bara)
• If not possible: Samson 3730-0 positioner
Please note that for proper functioning of the pump or valve the MFC needs to be adjusted electrically and also
needs to be provided with the right parameter settings. This will be taken care of in our factory.
For pump- or valve connections in the field after delivery, please contact your local sales representative.
