Description

The D2 FloPro control valve (figure 1) is a compact, rugged valve designed for on-off control of a variety of fluids at

pressures up to 155 bar (2250 psig). This valve is ideal for use as a dump valve on gas separators and scrubbers. It is

also well suited for other high pressure applications in natural gas production, compression, and processing. The D2

FloPro valve has threaded end connections and is available in an NPS 1 globe style valve body.
