An AISI 4130 gate valve is a heavy-duty, high-pressure isolation valve forged from low-alloy chromium-molybdenum steel, engineered specifically for severe-service upstream oil and gas applications. The AISI 4130 metallurgy undergoes specialized heat treatment to achieve high tensile strength, exceptional fracture toughness, and excellent weldability under intense mechanical loads. Featuring a slab or expanding wedge gate design, it provides an unobstructed, full-bore flow path when fully open, making it ideal for high-pressure drilling manifolds, wellhead Christmas trees, and mud systems. These gate valves are built to withstand working pressures up to 10,000 psi or 15,000 psi in sour gas and oil environments. Project engineering teams and refinery procurement networks can ensure absolute pressure containment and long-term joint integrity by importing certified AISI 4130 gate valves directly from premier manufacturers in China via our advanced B2B commercial platform.
