Altecnic 11/2" Prescal Pressure Reducing Valve

High pressure rating and available up to 2". Dial-up pressure setting. Tilted design for quieter operation.

Pressure reducing valves are installed in residential water systems to reduce and stabilise inlet pressures from mains water supplies or boosted water systems, which generally are too high and variable for domestic appliances to function correctly.

The 535 series is specially designed for hot and cold services in semi-commercial or public buildings to equalise either the hot or cold supplies or both and prevent excessive pressure at water outlets such as taps, basins, toilets, dishwashers and other appliances.

The series 535 pressure reducing valves are pre-adjustable enabling them to be 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 is assembled as one unit to make removal for inspection, cleaning and maintenance operations easier.

The compensated seat design means that the set downstream pressure remains independent of upstream pressure variations.

The hydraulic profile of the valve makes it possible to achieve low pressure losses, even when a large number of outlets are open.

The control stem housing of the cartridge is made from a plastic material with a low co-efficient of adhesion, which reduces the probability of scale deposits forming, the main cause of pressure reducing valve malfunction.

  • Maximum pressure at inlet : 16 bar
  • Outlet adjustment range : 1 - 6 bar (static control only)
