The SKP20.130... operates as a balanced gas pressure governor and controls the gas pressure according to the pressure of the combustion air so that the gas / air ratio remains constant over the entire load range (shifting the setpoint by the static pressure of the combustion air). Therefore – in contrast to conventional gas / air ratio control – air volume changes due to mains pressure variations, soiled fan wheel, etc., have no impact on the quality of the combustion process.
The gas pressure governor consists of
The setpoint adjustment can be sealed.
The impulse pipe connection is Rp1/4.
The housings of actuator and governor are made of die-cast aluminium and the seals are made of elastomer. |
