Siemens VGD20.. and VGD40.. gas valves - with SKP2.. (pressure governor)
Mounting
z
When mounting the VGD.. double gas valve, two flanges are required (as for VGD20.. model, the flanges are threaded);
z
to prevent cuttings from falling inside the valve, first fit the flanges to the piping and then clean the associated parts;
z
install the valve;
z
the direction of gas flow must be in accordance with the direction of the arrow on the valve body;
z
ensure that the bolts on the flanges are properly tightened;
z
ensure that the connections with all components are tight;
z
make certain that the O-rings and gaskets between the flanges and the double gas valve are fitted.
z
Connect the reference gas pipe (
TP
in figure), to the gas pressure nipples placed on the gas pipe, downstream the gas valves: gas pres-
sure must be measured at a distance that must be at least 5 times the pipe size .
Leave the blowhole free (
SA
in figure). Should the spring fitted not permit satisfactory regulation, ask one of our service centres for a
suitable replacement.
