Description
The D3 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. NPS 1 and
NPS 2 D3 FloPro control valves are available in CL900 NPT end connections and CL600 raised face flanged end
connections.
