The Berluto DRV 200 / DRV 200 G is a diaphragm, spring-loaded, single-seat pressure reducer without pressure relief. Adjustment is mechanically achieved via the spring and outlet pressure, requiring no auxiliary energy or impulse line. Primarily designed for compressed air and neutral gases, it can also be used with water or neutral liquids for small flow rates.
The body is made of red bronze CC499K. Wetted parts are brass. The spring cap is brass up to DN25 and cast iron from DN32. The diaphragm is CR, and seals are NBR, with a temperature limit up to 100°C.
The main difference is the lower outlet pressure setting range. DRV 200 covers 1.5–8 bar, while DRV 200 G covers 0.8–8 bar. Selection depends on required downstream pressure, flow rate, and Kvs of the respective DN.
Installation position can be any, with a preference for vertical placement. Dual G 1/4” gauge connections are available for outlet pressure indication. Internal and external surface treatments include nickel plating, chrome plating, or chemical nickel plating.
Used in compressed air lines, neutral gases, auxiliary machine circuits, small water flows, and neutral liquids where local pressure reduction with simple mechanical adjustment is required.
Pressure reducing valves of the series are diaphragm-controlled, spring-loaded pressure reducing valves. The series has a high setting accuracy and good response behaviour due to their low friction of the few moving internal parts.
Nominal size DN 8 to DN 50
Inlet pressure up to 25 bar
Outlet pressure from 0,8 up to 8 bar
Temperature range -15°C to 100°C
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.
