Emerson Process Management”s Fisher Design D3 FloPro high-pressure, on-off control valve is a globe-style valve designed 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 valve is available in one- and two-inch Class 900 NPT end connections and two-inch Class 600 raised-face flanged end connections. With its ENVIRO-SEAL packing technology, the valve offers a long stem seal life. Rugged construction details, like heavy-duty valve plug guiding and optional ST (super-tough) Carbide trim, provide a long service life. Fisher ST Carbide trim is designed specifically for severe service applications. Low temperature-tolerant materials allow applications as low as -46 C (-50 F). The standard trim, valve body, and bonnet meet the metallurgical requirements of NACE MR0175/ISO 15156.
