Large Caliber Forged Steel 3-Piece Flanged Ball Valve

Zhejiang Chenxiang Valve Co., Ltd. presents our large caliber forged steel 3-piece flanged ball valve for major pipeline systems. This product serves main pipelines, tank farm inlets and outlets, and long-distance transmission lines. These systems typically need large diameter valves from DN200 to DN500. The machining precision and testing capability for these large valves reflect the true strength of a valve factory. Our product handles diameters up to 20 inches. The product serves petroleum, chemical, natural gas, light industry, power, pharmaceutical, metallurgy, water supply, and military sectors. It handles compressed air, natural gas, coal gas, LPG, nitrogen, oxygen, hydrogen, steam, flue gas, and various process tail gases. Our models include Q047N, Q347PEEK, Q347Y, Q947Y, and Q647Y.

Our large caliber forged steel 3-piece flanged ball valve uses body materials like A105, F304, F316L, LF2, F11, F22, F53, F55, 4A, 5A, Inconel, Monel, 2205, 2507, 904L, copper alloy, titanium alloy, Hastelloy, and nickel alloy. We recommend worm gear, pneumatic, electric, or hydraulic drives for this large size. Manual operation is not recommended. Connections are RF, FM, G, M, or RTJ. The structure is a trunnion ball valve. Trunnion types meet DIB-1 and DIB-2 standards. Our factory has large CNC vertical lathes and boring-milling machining centers. These machines can process valve bodies over one meter in diameter. We also have high-tonnage pressure testers for large diameter valve testing. Surface treatment includes shot blasting. This process improves paint adhesion for better corrosion protection.

We support OEM and ODM for our product. The minimum order quantity depends on the specific size. Please consult us for details. Free samples are available, but shipping costs are negotiable. Delivery takes 25 days. Our monthly production capacity is 2000 to 5000 units. Choose our large caliber forged steel 3-piece flanged ball valve for your major pipeline and tank farm projects.
