The hard-sealed butterfly valve is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
The Bellows Seal Gate Valve is a high-performance valve designed to ensure sealing integrity and prevent medium leakage. It utilizes bellows seal technology to effectively block fluid leaks that could cause environmental pollution or safety hazards. This valve is suitable for use in steam, thermal oil systems, heat exchangers, and other high-temperature, high-pressure fluid control applications. Its compact structure and easy maintenance offer long-term reliable sealing performance.
