Here are the key factors to evaluate. ### Forged vs. Casting Forged gate valves offer higher strength for small-bore, high-pressure lines. Casting is more cost-effective for larger sizes and standard pressures. ### Wedge Type Solid wedge for general service; flexible wedge for thermal cycling; double disc (parallel slide) for high-temperature steam systems. ### Bonnet Design Bolted bonnet is standard. Pressure seal bonnets suit Class 600+ applications. Bellow seal bonnets prevent fugitive emissions for toxic media. ### End Connection Flanged for easy maintenance; butt weld for permanent, leak-free joints; threaded/SW for small-bore instrument lines.

What certifications do XINTAI gate valves hold?+ XINTAI gate valves hold API 600, API 602, API 6D, ISO 9001, ISO 14001, ISO 15848, ISO 45001, CE/PED, SIL, PAT, and TAT certifications — ensuring compliance with standards required by major EPC contractors worldwide. What size range do XINTAI gate valves cover?+ Our gate valves range from 1/4″ (DN8) to 56″ (DN1400), covering ASME Class 150 to Class 2500 and DIN PN16 to PN63. Custom sizes and ratings are available upon request. What is the difference between forged and casting gate valves?+ Forged gate valves are made from solid steel billets under high pressure, offering superior strength and a tighter grain structure — ideal for high-pressure, small-bore applications (typically up to 4″). Casting gate valves are produced by pouring molten metal into molds, making them more cost-effective for larger sizes (2″ and above) and standard-pressure service. What is a bellow seal gate valve?+ A bellow seal gate valve uses a metal bellows welded to the stem and bonnet to create a hermetic seal, completely preventing fugitive emissions through the packing area. It is widely used in toxic, flammable, radioactive, or environmentally sensitive applications where zero leakage to atmosphere is required. Can XINTAI provide custom gate valve solutions?+ Yes. We offer full customization including special alloy materials (Inconel 625, Monel 400, Duplex 2205, Super Duplex 2507, titanium), extended bonnets for cryogenic service, NACE MR0175 sour service compliance, and custom actuation packages with pneumatic, electric, or hydraulic actuators. What is the typical lead time for gate valve orders?+ Standard gate valves typically ship within 15–30 days after order confirmation. Large-diameter, high-pressure, or custom-material valves may require 30–60 days. We maintain stock of common sizes for faster delivery. Do you support third-party inspection?+ Absolutely. We welcome inspections from SGS, Bureau Veritas, Lloyd’s Register, TÜV, and other agencies. Our testing center is equipped for hydrostatic, pneumatic, and fire-safe testing per API 607. ## Ready to Source Gate Valves from China?
