Honeywell Pressure Reducing Valves

Honeywell pressure reducing valves lower mains or booster pressure to a constant value the installation can handle safely, protecting taps, cisterns, boilers and water heaters from excess pressure. This page lists the Resideo (Honeywell Home) threaded D06F family, the compact D04FM and D05FS, the flanged D15S series and the D22 for compressed air.

How to choose a Honeywell pressure reducer

Check the pipe size, the inlet pressure and the required outlet pressure. An outlet range of 1.5–6 bar covers most homes; special models exist for very high or very low outlet pressures.

See all brands in the pressure reducing valves category. Popular items: the D06F lead-free pressure reducer with unions and the stainless steel D06FI. For a filter and pressure reducer in one body, see FK06 and FK74CS in water filters. More on the Honeywell brand page.

All products are original and supplied with an invoice; the warranty is provided by the manufacturer or importer. The current price is shown on each product card: the VAT-inclusive price first, the VAT-exclusive price below it.

Frequently asked questions

What outlet pressure can D06F be set to?

D06F is adjustable between 1.5 and 6 bar with a setting scale on the body. Choose D06FH (1.5–12 bar) for higher or D06FN (0.5–2 bar) for lower outlet pressure.

Which Honeywell reducer has a strainer?

The D06F family has a built-in strainer with 0.16 mm mesh. For a backwash filter combined with a pressure reducer, choose FK74CS; FK06 is the simpler combination.
