When the adove controls have been carried out, the 
valve can be fitted in line, making sure that the body 
is oriented so that the flow is in the direction shown by 
the arrow impressed on the body itself. For proper 
regulation, it is indispensable for the downstream 
sensing line to be connected to a rectilinear strech of 
the downstream piping itself with a length in 
accordance with the fig. 5 and 6 and with a maximum 
gas speed at the take-off point not exceeding 30 
m/sec.

 

The following is recommended so as to prevent the 
accumulation of impurities and condensate in the 
lines of the pressure take-offs:

 

a) the piping itself must slope down towards the down 

stream connectors with a slope of about 5-10%; 

b) the connectors on the piping must always be 

welded on the top of the piping itself and there 
must be no burr or inward protrusions in the hole in 
the piping. 

 
N.B.  DO NOT PUT ON/OFF VALVES ON THE 

IMPULSE TAKE-OFFS

 

The most common types of installation for the SBC 
782 cut-off device are shown in figures 5 and 6. 
Figure 5 shows installation in a pressure regulation 
line, figure 6 shows installation on a generic trunk.
