The Berluto DRV 724 and DRV 725 are direct-acting, piston-operated, spring-loaded, single-seat pressure reducers with inlet pressure compensation. Downstream pressure is mechanically regulated without external energy or impulse line. The cartridge design allows for replacement of internal components during maintenance.
The body and spring cap are made of stainless steel 1.4408. Wetted internal parts are stainless steel 1.4404. Seals are available in NBR up to 100°C, FKM up to 190°C, and EPDM up to 130°C for DN40–DN50 only.
The series is used in aggressive water and other aggressive liquids. It can also be applied to air and neutral gases when the required flow is covered by the available Kvs.
DRV 724 is selected for downstream pressure 1.5–12 bar. DRV 725 covers a higher set point, 2–20 bar. Selection requires p1, p2, flow rate, DN, Kvs, temperature, medium, and elastomer compatibility.
The valve features an integrated filter and dual gauge connection G 1/4” for outlet pressure indication. Installation position can be any, with a preference for vertical. The technical datasheet references PED 2014/68/EU and 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.
