The MPN 36ELF11401T model represents a factory-calibrated water pressure regulator specifically engineered to maintain a consistent 75 pounds per square inch downstream output, delivering reliable pressure reduction for residential and commercial drinking water distribution systems where municipal supply lines exceed safe operating thresholds. This 3/4-inch threaded connection pressure reducing valve functions as a critical barrier between high-pressure water supply mains and vulnerable household plumbing infrastructure. The 75 PSI calibration point positions this valve precisely at the upper boundary of recommended residential water pressure ranges, making it ideal for applications requiring robust flow rates while maintaining equipment protection. The valve's three-quarter inch NPT female inlet and outlet connections accommodate standard residential pipe sizing throughout North American plumbing installations. This dimensional specification ensures compatibility with existing water supply infrastructure without requiring extensive pipe modifications or custom adapter fittings during retrofits. Lead-free brass construction throughout the MPN 36ELF11401T body assembly guarantees compliance with NSF/ANSI 372 drinking water safety standards, eliminating heavy metal contamination risks in potable water systems while providing superior corrosion resistance across decades of continuous service. The precision-set 75 PSI downstream pressure setting protects water heaters, washing machines, dishwashers, and other appliances rated for maximum 80 PSI operating pressures. This specific calibration creates a protective buffer zone between equipment warranty thresholds and actual delivered water pressure measurement values. Factory preset calibration eliminates field adjustment requirements, ensuring immediate installation readiness without specialized pressure testing equipment or technical expertise. The fixed 75 PSI setpoint prevents accidental over-adjustment that could compromise plumbing system protection or create excessive pressure conditions. Cast Copper Silicon Alloy Body Construction Delivering Superior Structural Integrity & Corrosion Resistance for Extended Service Life The MPN 36ELF11401T valve body utilizes cast copper silicon alloy metallurgy, providing exceptional strength-to-weight ratios while resisting dezincification corrosion that degrades standard brass components in aggressive water chemistry environments containing elevated chloride or sulfate concentrations. This specific alloy composition eliminates lead content completely, surpassing Safe Drinking Water Act requirements that mandate less than 0.25% weighted lead content in wetted plumbing surfaces. The casting process creates a monolithic body structure without welded joints or potential leak paths, concentrating material density around high-stress threaded connection zones. This manufacturing approach prevents cracking under thermal expansion cycles and water hammer shock events that fracture welded assemblies over time. Three-quarter inch female NPT threads machined to ANSI/ASME B1.20.1 specifications ensure proper engagement with male pipe threads, creating reliable mechanical seals when combined with appropriate thread sealant compounds or PTFE tape applications. The female-to-female thread configuration simplifies installation by allowing direct threaded connection to existing male-threaded supply piping without requiring union fittings or additional connection hardware. This design reduces total installation length, making the valve suitable for confined mechanical room spaces or shallow meter pit installations. Surface treatment processes applied to the copper silicon alloy body enhance corrosion resistance in outdoor waterworks pit installations where moisture exposure and soil contact create aggressive environmental conditions. The protective finish prevents pitting corrosion that compromises pressure boundary integrity in buried valve applications. Reinforced EPDM Diaphragm Mechanism Providing Precise Pressure Regulation Through Spring-Loaded Force Balancing Technology The pressure regulation mechanism within MPN 36ELF11401T employs a reinforced ethylene propylene diene monomer diaphragm assembly that responds proportionally to downstream pressure fluctuations, automatically modulating flow restriction to maintain the calibrated 75 PSI setpoint regardless of upstream pressure variations.
