FAQ - Forged Globe Valve 900LBS – 1500LBS (NPT, SW Ends)

Q1: What is the difference between Class 900 and Class 1500 forged globe valves?

A: Class 900 has a design pressure of 153 bar (2,220 psi), suitable for high-pressure steam, oil and gas transmission. Class 1500 has a design pressure of 260 bar (3,750 psi), designed for ultra-high-pressure steam, gas injection and wellhead equipment. Class 1500 uses thicker walls and heavier trim for more demanding service.

Q2: Why are Class 900 and 1500 combined on this page?

A: Class 900 and Class 1500 share the same NPT and SW end connection standards and similar body construction in API 602. Combining them on one page helps engineers compare the two pressure classes directly and select the right one for their application without switching pages.

Q3: When should I choose SW over NPT for Class 900 and 1500?

A: Choose Socket Weld (SW) for permanent, leak-tight high-pressure installations where welding is possible and no future disassembly is expected. Choose NPT (Threaded) for applications requiring easy installation and removal. For Class 1500, SW is generally preferred for critical high-pressure service.

Q4: What is the difference between full bore and reduced bore?

A: Full bore (FB) has a bore equal to the nominal pipe size, minimizing pressure drop and allowing pigging. Reduced bore (RB) has a smaller bore, resulting in a more compact and lighter valve at lower cost, with slightly higher pressure drop. Both are available for Class 900 and 1500 forged globe valves.

Q5: What materials are available for Class 900 and 1500 forged globe valves?

A: Standard body materials include carbon steel (A105, LF2), alloy steel (F5, F11, F22), stainless steel (F304, F316) and duplex stainless steel (F51). Trim options include 13Cr, Half Stellite, Full Stellite, SS304 and SS316. Material selection depends on operating temperature, pressure and fluid corrosiveness.

Q6: Is NACE MR 0175 available for Class 900 and 1500 NPT/SW globe valves?

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