FAQ - Forged Steel Flanged Gate Valve (150LBS – 2500LBS, Flanged and BW Ends)

Q1: What is the difference between flanged and butt weld (BW) ends on this valve?

A: Flanged ends allow easy installation and removal without welding, making them ideal for pipeline systems requiring frequent maintenance. Butt weld (BW) ends provide a permanent, leak-tight connection preferred for high-pressure and high-temperature applications. Both are available in sizes 1/2 inch to 2 inch with Class 150 to 2500 coverage.

Q2: What is the face-to-face dimension standard for this valve?

A: Face-to-face dimensions comply with ASME B16.10 for flanged gate valves (short pattern). RF and RTJ facing share the same FTF dimensions. The dimension table above provides values for Class 150 through Class 2500. Contact us for confirmed drawings.

Q3: How do I choose the pressure class for my application?

A: Class 150 to 300 suits low to medium pressure utility and process lines. Class 600 to 900 fits general high-pressure process, refinery and power plant service. Class 1500 to 2500 is for high-pressure steam, gas injection, wellhead equipment and natural gas compressor lines. Final selection depends on design pressure, temperature and material derating.

Q4: What is the difference between integral flange and welded flange?

A: Integral flange is forged together with the valve body, providing higher strength and better leak-tightness for high-pressure applications. Welded flange is welded onto the valve body, offering more flexibility in flange facing and material combinations. Both are available for choice.

Q5: What materials are available for this forged steel flanged gate valve?

A: Standard body materials include carbon steel (A105, A105N, LF2), alloy steel (F5, F11, F22), stainless steel (F304, F304L, F316, F316L) and duplex stainless steel (F51, F53). Trim options include 13Cr, 304, 316, hard faced and full hard faced. Material selection depends on operating temperature, pressure and fluid corrosiveness.

Q6: Is NACE MR 0175 available for sour service?

A: Yes, NACE MR 0175 compliance is available on request for sour oil and gas applications. This includes material selection, hardness control and testing requirements to ensure resistance to sulfide stress cracking. Please specify NACE MR 0175 in your inquiry.
