DAC Worldwide's Wellhead Backpressure Regulator Cutaway (295-703) is a sectioned specialty regulator example allows for convenient classroom and laboratory training in the operation, construction, and maintenance of three industrial back pressure regulator (BPRs), as used in gas and oil service in the oilfield. These common regulators are often used to maintain steady pressure on an oil column, assure continuous flow of a producing low pressure well, and are regularly found in Xmas tree assembles in the oilfield. Through carefully-planned sectioning and color-coding, the complete internal configuration of the regulating valve is exposed and showcased. Seal features and hardware locations have been retained, allowing for “hands-on” training in maintenance. These valves, commonly used in oil & gas production applications and commonly encountered in production wellheads, and christmas trees, would be of interest to those involved in oil & gas production training.
