The Honeywell D04FM Pressure Reducing Valve with Gauge is designed to help maintain controlled water pressure in compatible plumbing and water supply systems. By reducing excessive incoming pressure to an appropriate downstream level, it can help protect connected pipework, fittings and appliances from the effects of unnecessarily high water pressure.
Featuring an integrated pressure gauge with a 0–160 PSI scale, the valve allows convenient visual monitoring of pressure at the gauge location. This makes it easier to check system conditions and assess pressure during installation, adjustment and routine maintenance.
The valve is supplied with dual-thread connections comprising a 1/2-inch BSP female thread and a 3/4-inch BSP male thread, providing connection options for compatible plumbing arrangements. Its integrated design brings pressure reduction and pressure monitoring together in a single assembly.
Ideal for suitable plumbing installations where pressure control is required, the Honeywell D04FM offers a practical solution for installers, maintenance professionals and property owners. Always verify the connection sizes, operating pressure range, water compatibility and installation requirements against the manufacturer's technical documentation before fitting.
