شیر یکطرفه فورج شده طرح API 602

The API 602 Pattern Forged Lifting Check Valve is designed for high-pressure, high-temperature applications in compact piping systems, particularly in industries like oil and gas, power generation, and chemical processing. Built to conform with API 602 standards, this valve features a compact, forged body for enhanced strength and durability in critical service conditions. The lifting check mechanism allows the disc to rise with forward flow and automatically seat with reverse flow, preventing backflow and protecting pumps and equipment. Its forged construction ensures better grain structure and resistance to stress corrosion, while the tight sealing performance minimizes leakage and pressure drop. Typically available in a variety of materials and end connections, this valve is suited for use in small-bore piping with severe operating conditions. The API 602 pattern emphasizes reliability, space efficiency, and long-term performance, making it a trusted choice for engineers and plant operators requiring robust flow control in demanding environments.
