Resideo ds06-101-sut-lf 3/4 in Pressure Regulating Valve

Product Description

The RESIDEO ds06-101-sut-lf is a 3/4-inch female NPT, single-union, internally threaded pressure regulating valve (PRV) designed to maintain a constant downstream pressure across a wide range of inlet supply pressures. Built on a bronze body with a fabric-reinforced diaphragm and stainless steel internals, this valve handles inlet pressures up to 250 psi and allows downstream pressure adjustment from 25 to 90 psi. The calibrated DialSet adjustment dial lets technicians set static outlet pressure without a separate gauge, streamlining the commissioning process. Licensed plumbers install this valve in potable water and irrigation systems where consistent pressure control is required.

This valve is suited for residential and light commercial potable water distribution and irrigation supply lines where a 3/4-inch pipe connection is present. The single-union threaded configuration allows the valve body to be removed and serviced without cutting the line. Two 1/4-inch NPT gauge taps, one on each side of the body, provide access points for inline pressure measurement when needed. The 10:1 maximum reducing ratio supports installations with high-pressure supply feeds that must be brought down to safe service pressures.

Key Features

• Calibrated DialSet adjustment dial sets outlet static pressure from 25 to 90 psi without a separate pressure gauge
• Maximum inlet pressure rating of 250 psi with up to 10:1 pressure reducing ratio
• 3/4-inch female NPT connections with external threading for single-union assembly
• Bronze body with fabric-reinforced diaphragm and stainless steel components for durability in potable water service
• Two 1/4-inch NPT gauge taps (one per side) for inline pressure monitoring
• NSF/ANSI, IAPMO, ASSE 1003-2009, and CSA (B356-10) certified for potable water applications

Compatibility

Designed for use in 3/4-inch potable water distribution and irrigation systems requiring pressure regulation; suitable as an OEM-style or replacement PRV where ASSE 1003-2009 compliance and female NPT single-union connections are specified.

Installation Notes

Installation must be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure completely before removing or installing the valve. The single-union design allows body removal for service without cutting pipe; ensure union threads are clean and properly engaged before restoring pressure. Operating temperature must not exceed 140 degrees F; verify supply conditions before installation in high-temperature applications.
