Sensus 243-12-1 1/4 Regulator 30067439-890 The intake side bore location

The intake side bore location is critical for proper hub-to-motor spacing within the fan orifice to ensure the 26 inch fan blade is centered correctly for optimal suction

even after repeated assembly and disassembly during routine HVAC system maintenance

Hard-drawn copper must be properly annealed before flaring or swaging to prevent cracking

or if the regulator fails to achieve a "bubble-tight" lock-up during a pressure test

Easy Installation: The 18" lead length and 11/32-32 male nut facilitate quick connections to Pilotstat controls without lead tension issues

Sensus 243-12-1 1/4 Regulator 30067439-890 The intake side bore locationThe Sensus 243 12 1 1 4 Regulator (equivalent to model 243 12 1 1 1 4) is a high capacity natural gas service regulator engineered for commercial and industrial applications requiring precise pressure control. Featuring a 1 1 4" NPT connection and a 3 4" orifice, this unit is designed to handle significant flow rates while maintaining a steady downstream pressure. The internal 6" to 14" w. c. outlet pressure range is established by the green spring,
