SKP70... series actuators can be combined with ½-inch to 5-inch VG... series gas valve
bodies. VG... series gas valves are ordered as separate items (See VG...U.. Technical
Instruction No. 155-512P25).
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 T-
fitting (See Figure 4, AGA78).
A motorized pressure reducing control (SQN37... ) can also be installed in the air
impulse line to continuously optimize combustion when used in conjunction with an
oxygen trim system.
