Specialized Configurations to Meet Your Needs

UBR regulators are available in a variety of special configurations to meet specific operational needs. One of these options includes the use of exotic materials such as duplex, superduplex, alloy steel, monel, and inconel, all of which can be supplied with short lead times. These materials are chosen for their superior strength and resistance to corrosion, making the regulators suitable for harsh environments.

For applications requiring precise control of pressure differentials, UBR regulators can be configured in differential versions, available with either single or double diaphragms. This allows for accurate regulation and maintenance of consistent pressure differences between two points in the system.

Additionally, special welding options, such as butt-weld (BW) or socket-weld (SW), are available for installations where unique or customized connections are required. These specialized features ensure that UBR regulators can be adapted to a wide range of industrial applications, providing both versatility and reliability.
