The SKP25 operates with a gas pressure governor and controls the gas pressure according to the setpoint preselected with the setpoint spring or air pressure signal.
Its field of use are primarily forced draft gas burners
• with mechanical air / fuel ratio control
(SKP25.0)
• with electronic air / fuel ratio control
(SKP25.0)
• with 2-stage setpoint changeover
(SKP25.2)
• with zero governor (SKP25.3)
• with constant pressure governor and
electric adjustment of the setpoint spring
(SKP25.7)
The SKL25 actuators are of the same design as the SKP25, but close more slowly (3 to 6 seconds).
The SKL25 do not conform to the standards for gas applications and, for this reason, are only suited for use with air.
