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.

    Instruction Manual D2 FloPro Valve D103031X012 June 2011 WARNING Avoid personal injury from sudden release of process pressure. If the process media starts to escape from the safety vent (see figure 2) located in the bonnet neck of the valve body, STOP DISASSEMBLY IMMEDIATELY! The escape of process media indicates that the valve has NOT been isolated from the process media, or process pressure is trapped in the valve body.
