We would like to forward explanation about outlet of valve and filling connection as below,
please kindly refer to it and let us have your comments.
1. We set specification of cylinder valve and filling connection based on CGA rule.
Cylinder valve is related with CGA V-1 "Standard for compressed gas cylinder valve outlet and lnlet connections" and filling connection is related with CGA V-10 "High Pressure Tube Trailer Connections".
2. In case of Cylinder valve, we applied CGA 580 valve as per CGA V-1 rule and TSG confirmed it.
3. In case of Main valve, it`s such kind of intercept valve so it`s not related with CGA rule.
please consider that it`s difficult to find such kind of main valve with CGA connector,
so we would like to use our suggestion orginally.
4. As we described, filling connection is related with CGA V-10 "High Pressure Tube Trailer Connections",
and as per the code, we applied CGA 1340 connection to their He tube skid, its specifiation is same with previous unit. CGA 580 is related with cylinder valve but not with fillilng connection, so we suggest to apply CGA 1340 connection which we offered originally to new order.
