Built from a lead-free copper silicon alloy body with a polymer seat, it delivers a standard factory setting of 50 psi and an adjustable range of 25 to 75 psi. Maximum working pressure is 300 psi. The valve features an NPT female union inlet paired with an NPT female outlet, making in-line installation and future maintenance straightforward. A built-in bypass feature manages thermal expansion pressure, helping prevent system stress in closed-loop configurations. Licensed plumbers install this valve as part of a code-compliant pressure regulation strategy.\u003c\/p\u003e\n\u003cp\u003eThis PRV is rated for residential, commercial, and industrial water service. Typical installations include the main domestic water service entry point, branch circuits serving fixtures sensitive to high pressure, and supply lines where local utility pressure regularly exceeds safe fixture ratings. The temperature rating of 33 to 160 degrees F covers standard cold and hot domestic water service ranges. The replaceable seat module allows field servicing without full valve replacement, reducing downtime in commercial settings where water service interruption is costly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free copper silicon alloy body meets lead-free compliance requirements for potable water service\u003c\/li\u003e\n  \u003cli\u003eAdjustable pressure range of 25 to 75 psi with a 50 psi standard factory setting\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure rated at 300 psi for high-pressure supply line compatibility\u003c\/li\u003e\n  \u003cli\u003eNPT female union inlet allows removal and reinstallation without cutting pipe\u003c\/li\u003e\n  \u003cli\u003eReplaceable polymer seat module supports in-field maintenance without full valve swap\u003c\/li\u003e\n  \u003cli\u003eIntegrated bypass feature controls thermal expansion pressure in closed systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install PRV for 3\/4 inch NPT threaded residential, commercial, and industrial potable water supply systems requiring adjustable downstream pressure control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the applicable edition of the International Plumbing Code (IPC). Shut off the main water supply and relieve system pressure before installation or seat module service. Install with flow direction matching the arrow cast on the valve body.
