Carraro - Control valve UBB
With valves in the UBB series, it is possible to achieve two different kinds of functions: Can work as a spring-loaded, direct acting pressure-reducing regulator or as a pressure-relief valve. The valve acts both pressure-reducing and counter-pressure controlling. Used in a wide range of industrial applications for process gases (including air). The large diaphragm provides accurate control even at low pressures, and the built-in lever principle provides good shut-off density. Easy to install and maintain due to the simple construction.
