ASTM A182 F304 Double Ball Valve, 40 IN, CL600, Full Welded

Built for high-pressure and large-diameter pipeline service, this trunnion-mounted ball valve is designed in accordance with API 6D and BS 5351 standards, ensuring safe and reliable operation in demanding industrial environments. The valve features a forged ASTM A182 F304 stainless steel body and trim, providing excellent corrosion resistance and long service life in aggressive media. With an extra-large 40-inch size, Class 600 LB / PN100 pressure rating, and RF flanged ends, it supports secure, leak-tight installation. The full-welded construction enhances structural strength and sealing integrity, while the trunnion design reduces operating torque and improves stability. As a leading Double Ball Valve Factory in China, we supply high-performance, precision-engineered flow control solutions.
