The Berluto DRV 602-6 is a flanged direct-acting pressure reducing valve designed for higher flow rates of potable water. It features a diaphragm, spring, and inlet pressure compensation for adjustment, eliminating the need for an external actuator or impulse line. The valve is single-seated, with downstream pressure continuously adjustable between 1.5–6 bar.
The body is made of red bronze CC499K, and the spring cap is cast iron. Wetted parts are brass, while the diaphragm and seals are EPDM with ELL and W270 approvals. Metal parts comply with the UBA positive list for potable water applications.
Suitable for potable water distribution zones, central building supplies, industrial installations with sanitary requirements, downstream network protection, and equipment supply requiring limited operating pressure.
Installation can be in any position, preferably vertical. Sizing requires p1, desired p2, peak flow, DN, Kvs, water temperature, flange PN, and available differential pressure. The technical datasheet references PED 2014/68/EU, DVGW, ISO 9001, and available classification approvals DNV GL, ABS, LR, CCS, and BV.

Technical data
CE-certification according to the European Pressure Equipment Directive is mandatory for numerous products and delivery areas. Other certificates, however, are certificates of individual quality, such as DVGW and DIN EN ISO 9001, which stands for the internal quality management system with its extensive functional and performance checks. The particularly strict regulations of the national rules and regulations guarantee the highest possible safety - especially when it comes to the reliability in your plant.
