Carraro S.r.l. products

The UBAN series are direct-operated, pressure reducing regulators. Their main function is to regulate the outlet pressure. They are available in 1/2 up to 2 inches (DN15 through DN50) body sizes and can be supplied with a wide range of different end connections. The bolted flanged design provides flexibility to meet custom face to face dimensions as required (easy to install / suitable for old valves replacement). These regulators have a compact design and durable construction to sustain rugged use and their construction makes them easy to install and to maintain.

The UBS series are spring loaded, direct-operated, pressure relief valves used downstream of pressure regulators to protect the downstream system from over pressure. Their main function is to regulate the inlet pressure. They can be used also as backpressure regulators as they have good throttling characteristics. They are available in ½ up to 2 inches (DN15 through DN50) body sizes. These regulators have a compact design and construction such to sustain rugged use and their construction makes them easy to install and to maintain.

The UBR series are ?high capacity? direct operated, spring loaded pressure reducing regulators. They are available in ½ up to 2 inches (DN15 up to DN50) body sizes and flanged end connections. The flanged version is designed with ISA face to face dimensions. These regulators have a compact design and durable construction to sustain rugged use and their construction makes them easy to install and to maintain.

The UBB series have the possibility to accomplish two di.erent kind of functions: they can work as spring loaded, direct-operated pressure reducing regulators or relief valves. This valve provides pressure reducing and backpressure control in a wide variety of industrial applications dealing with all kind of process gases (including air). The large diaphragm area provides more accurate control at low pressure settings and the lever design provides very good shut-o. tightness. These regulators are available in Vi up to VA inches body sizes. The simple construction makes it a very .exible and price-competitive item, easy to install and to maintain.

The UBAS/HP is a, spring loaded, direct-operated, pressure relief valve. Its typical application is on auxiliary pneumatic systems for rotating machines. This regulator has a very compact design and it has a very high inlet maximum pressure, so to be able to withstand system overpressures without damage.

Safety valve with nozzle and double blow down adjusting ring. The double ring increases the blow down and overpressure performances.

Respect to normal ``pop action`` safety valves, these particular valves open progressively in a proportional way thanks to a system of internal cages. This particular action prevents the water-hammer effect, very dangerous for the plants. The CS35 are therefore ideal for very viscous liquids (e.g. oil ISO VG 32 and 46) and this makes them very suitable for lube-oil systems and the petrochemical industry.

Special safety valve with electropneumatic command that can be self- or servo -actuated. This is a `sacrifice` valve particularly suitable for the start-up phase of the plants that, instead of normal safety waives, can be also isolated on the line (e.q. for maintenance).

Safety valve with single blow down adjusting ring and very compact design.

Special device for the steam temperature control and reduction thanks to the injection of perfectly atomized water through a variable injection area. Possibility of purchasing the `bare shaft` version (without actuator) which allows the installation of the actuator chosen by the client.
