- To be used with dual pressure valves.
Note : regulating range for above models is 0-120 PSI. For other ranges see technical data page.
Main valve body assembly must be external pilot model. Pilots
are supplied internally from primary pressure in regulator block.
Cannot field convert regulator block from Single Pressure to dual
pressure. Body/Block to base mounting screw #35336.
