Forged steel low-temperature ball valves are designed specifically for low-temperature environments and are primarily used for medium control in industrial pipelines such as power plants and chemical industries. Their core features include high temperature and pressure resistance, self-sealing design, and wear resistance.

Applicable Medium and Temperature

Suitable for non-corrosive media such as water and steam, operating temperature range is typically -40℃ to -196℃, with some models capable of adapting to even lower temperatures.

Structure and Design

‌Material: Valve bodies are forged from steel (e.g., A352 LF2/F316L), with sealing surfaces cladded in hard alloys (e.g., Stellite), hardness exceeding HRC60, providing excellent wear and低温 erosion resistance.‌

Sealing Technology: Utilizes bellows sealing and a split-type floating gate design, reducing the risk of low-temperature leakage. The sealing reliability enhances with increasing pressure.

‌Low-Temperature Compatibility: The valve cover extended neck design minimizes heat transfer, optimizes gate guide structure to reduce friction, and prevents cold brittleness damage.‌

Pressure Ratings and Standards

Pressure ratings cover from 1.6MPa to 14.0MPa (150LB-800LB), conforming to international standards such as API 602, MSS-SP-118, and inspection & testing are based on API 598 specifications.

Application Scenarios

Primarily used for cutoff control of low-temperature media in power plant systems, petrochemicals, LNG receiving stations, and offshore platforms.
