Rated 5 out of 5 by from German made Just replaced a brand new altech prv with this Honeywell branded one works so much better handles the incoming pressure better bearing in mind this is operating at its maximum of 16bar coming into the property and knocking it down to 3 bar. Needle stays steady unlike the brand new altech prv it's replaced which fluctuated and screeched as water passed through it.

Rated 1 out of 5 by from Not the product in the picture I ordered this but received something completely different and returned it straight away. Wasn't a Honeywell, had a plastic pressure gauge and absolute rubbish. Don't buy!

Pressure gauge

Why is this advertised with a brass threaded pressure gauge yet you sell it with a plastic one. Isn’t that miss selling I’d like the one I thought I was buying rather than a cheap plastic one that can split.
Asked by: Toolstation12249

What size threat is the gauge

Is the gage ¼ or ⅜
Asked by: Welshyeti

What is the flow rate at 5.5 bar in 3.5 bar out ?? Have you any p/v curves for these valves

Need to know flow rate for both 15 and 22 mm valves to ensure adequate supply to hot water cylinder and a bath and shower. I have purchased 15mm PRV but am apprehensive that this will supply required amount of water from a water softener.
Asked by: HY123

I'm looking to use this PRV on a caravan site that supplies water direct to the pitch. Will this valve keep the set pressure say 2.5bar when everything in the caravan is turned off, or will the pressure creep?

Asked by: jennjenn

does this alter litres per minute

I have a combi boiler which will only heat the water sufficiently hot at 10 litres per minute but my supply is giving 16 lpm will this valve reduce the flow to 10 lpm?
