NOTES:
•
Flange mount C6097s:
–
CANNOT be used for low gas pressure on the SV2 Series valves.
–
Can be used for high gas pressure and/or VPS as specified above.
–
The two (2) M4x25 Phillips head drive screws (included with SV2 Series valves) MUST be used to secure the flange
mount C6097 pressure switches to the SV2 Series valves.
•
NPT or Rp mount C6097s (¼ inch):
–
May be used for VPS, high gas pressure and/or low gas pressure mounted via piping and reducing means as specified
above.
–
Pressure taps on the SV2 Series valves are 1/8 in (3mm) NPT or BSP, depending on which port thread is ordered from
the factory. Refer to
Fig. 1
Valve nomenclature for further information. Digit # 6 in the valve model identifies the port
thread type.
–
Flange pressure taps are 1/8-27 in (3mm) if an NPT flange is ordered or 1/8-28 in (3mm) if a BSP flange is ordered
from the factory.
•
C6097 pressure switches cannot be used for VPS on valve models with external VPS functionality, when this feature is
enabled (valves with intelligent feature designation of 6 as identified by the 9th digit in the valve model number in
Fig. 1
Valve nomenclature; the SV2 Series Pressure Module must be used for these functions when they are enabled.
Mounting
The flange mount C6097s may be directly mounted on the SV2 Series valves in any of the four (4) positions on the valve body
and are keyed for specific mounting orientation. The seal of the flange mount C6097s are designed to cover the center pressure
access ports only of each mounting location. If using the flange mount versions, the two (2) M4x25 Phillips head drive screws,
shipped with all SV2 Series valves, must be used instead of the 8-32 screws shipped with the flange mount C6097 pressure
switches.
NPT or Rp mount C6097s may be connected to various valve or flange pressure taps as specified in
Table 10
and
Fig. 16
. Note
that available mounting locations and functions are valve model dependent.
Wiring to the C6097 pressure switch must be completed as well. Refer to the applicable C6097 document for wiring instructions.
