535 pressure reducing valves are pre-adjustable enabling them to set at the required discharge pressure prior to
installation, by means of the adjustment knob with pressure setting indicator.
The internal cartridge and control knob mechanism are assembled as one unit making removal for inspection,
cleaning and maintenance easier.
The compensated seat design means the set downstream pressure remains independent of upstream pressure
The 535 series of pressure reducing valve is certified according to BS EN 1567 for operating with inlet water
temperatures up to 40˚C.
