• Switching between the settings “Operation,

Venting and Blowing-off” should be as per

shown in the illustrations.

• During operations of the Gauge Cock like,

operation at low or extreme temperatures,

re-adjustment of the Cock may be required to

guarantee the tightness.

• Re-adjustment is done by carefully unscrewing

the collar Nut Clock with the help of an

adjustable spanner.

Operation And Maintenance :

Installation :

• The Gauge Cock is to be installed as per

approved installation rules of technology. The

connection to the pipeline is always on the

hexagon side.

• Suitable flat seal has to be installed between

the Gauge Cock and the Pressure Gauge.

• As an alternate, the Pressure Gauge can be

tightened by screwing into the Gauge Cock

with suitable thread sealant.
