Model UBS -Direct Operated Pressure Relief / Backpressure Valve

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.
