Siemens SKP75 Gas Actuator
The SKP75.xxxUx controls the burner manifold gas pressure as a function of the combustion air pressure. There is no need for an upstream constant pressure regulator when using an SKP75.xxxUx actuator within the acceptable pressure range of the VGxxx.xxxU gas valves bodies.
If the combustion air pressure exceeds the permissible value of 12" or 20" w.c. (see Specifications), the pressure must be reduced by means of a pressure reducing Tfitting AGA78.
