Forged Gate Valve 1500LBS – 2500LBS Applications

• Ultra-High-Pressure Steam: Main steam isolation, steam injection and boiler blowdown on small-bore ultra-high-pressure lines requiring maintainable BB design.

• Oil and Gas Wellhead: Wellhead control panels, gas injection and chemical injection lines at Class 1500 and 2500.

• Power Generation: Ultra-supercritical boiler drain, air vent and sampling line isolation on small-bore piping.

• Hydraulic Systems: High-pressure hydraulic control panels, test stands and oil and gas hydraulic power units requiring trim maintenance.

• Petrochemical: Hydrocracking, hydrotreating and ultra-high-pressure reagent injection lines.

• Chemical Processing: Ultra-high-pressure reagent feed, catalyst injection and corrosive fluid isolation.

FAQ - Forged Gate Valve 1500LBS – 2500LBS (BB, SW Ends)

Q1: Why choose Bolted Bonnet (BB) over Pressure Seal Bonnet (PSB) at Class 1500 and 2500?

A: Bolted bonnet (BB) allows easy access for trim inspection and replacement without replacing the entire valve, making it cost-effective for maintenance-prone service. PSB uses internal pressure to self-seal, providing superior leak-tightness but requiring the whole valve to be replaced if trim needs repair. Choose BB for maintainability, PSB for ultimate sealing performance.

Q2: Why is Socket Weld (SW) the only end connection offered on this page?

A: At Class 1500 and 2500, SW provides a permanent, full-penetration welded connection that can withstand the highest pressures and vibration. Threaded (NPT) ends are not recommended at these pressure classes due to leak risk. BW is also available on request for larger bore piping.

Q3: What is the difference between Class 1500 and Class 2500 forged gate valves?

A: Class 1500 has a design pressure of 260 bar (3,750 psi), suitable for ultra-high-pressure steam, gas injection and wellhead equipment. Class 2500 reaches 430 bar (6,250 psi) for the most demanding ultra-high-pressure applications. Class 2500 uses thicker walls, heavier trim and larger face-to-face dimensions (e.g., 2 inch: 279 mm vs 216 mm at Class 1500).

Q4: What trim options are available for Class 1500 and 2500 BB forged gate valves?

A: Standard trim options include 13Cr (1#), Half Stellite (5#), Full Stellite (5#), SS304, SS316, F51 and F53. Half Stellite is suitable for moderate erosive service, Full Stellite for severe erosive and high-temperature service, and stainless steel trim for corrosive media. Trim selection depends on operating temperature, pressure and fluid corrosiveness.

Q5: What materials are available for Class 1500 and 2500 BB forged gate valves?

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). Material selection depends on operating temperature, pressure and fluid corrosiveness.

Q6: Is NACE MR 0175 available for Class 1500 and 2500 BB SW gate 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.
