The Altecnic 533 Series pressure reducing valve with compression ends and a gauge port of 15 mm was created specifically for hot and cold services in homes or flats to balance the hot or cold water supply or both and prevent too much pressure at outputs like taps and showers. They have a specifically designed diaphragm for precise pressure adjustment in reaction to variations in downstream pressure. Water noise may be effectively reduced by the bigger outlet chamber's low departure velocity. The pressure lowering valve's primary fault is caused by scale deposits, which are less likely to form since the control stem housing of the cartridge is composed of a plastic material with a low coefficient of adhesion.
