Description
This gas valve is a compact automatic control unit with a flanged connection and 23 mm inlet/outlet diameter. It has a flow capacity of 4.6 m³/h at a pressure drop of 5 mbar. Maximum inlet pressure is 60 mbar; maximum operating pressure is 45 mbar, and the first valve closes against 50 mbar back pressure. The valve supports switchable softlite technology (pressure -3.5/+0 mbar), includes an input screen and pressure test points on both sides, and is intended for Ferroli Pegasus F3 boilers (N 153-170-187-221-255-189 2S).

| Mounting Feature | two threaded mounting holes at the base |
| Operating Principle | automatic control of gas outlet pressure |
| Output Pressure Stability | stable outlet pressure regardless of inlet pressure changes |
| Pressure Measuring Fittings | outer diameter 9 mm on input and output sides |
| Safety Feature | closure of main valve on power failure or gas supply |
| Valve Classification | safety valve class A/B; main valve class B/C/J per EN 161 |
Choosing and fitting
Parts of this type are selected by connection type, inlet/outlet diameter, closing variant (e.g., B+B, B+J), and the configuration of the two electrical actuating devices. They are mounted vertically with the actuators on top; tilting up to 90° from vertical may be allowed. Before ordering, match the pressure sensor pipe connection and compare the valve's maximum operating pressure to the system settings.
