Product Overview
The 80FWJ1.6P hydrogen bellows globe valve is a high-quality, highly reliable dedicated pipeline control valve developed for hydrogen piping systems in power plants. It has a nominal diameter of DN80 and a nominal pressure of PN16, adopting a standard flange connection structure. It is mainly applied to critical working conditions such as hydrogen cooling systems of generator sets and hydrogen transmission pipe networks, to precisely control the on-off and shut-off of hydrogen medium. As a core pressure-bearing equipment, it ensures the airtight, safe and stable operation of power plant hydrogen systems.
Optimized structural design is adopted to accommodate the special properties of hydrogen, including strong permeability, flammability and explosiveness. Compared with ordinary globe valves, it delivers superior sealing performance, safety performance and working condition adaptability, fully meeting the stringent requirements for long-term continuous operation of power station hydrogen systems.
Core Structural Advantages
The valve features a bellows-sealed core design, which fundamentally differs from traditional packing sealing structures. It effectively eliminates micro-leakage of hydrogen medium through the valve stem, boasting outstanding advantages of zero external leakage and stable sealing performance, and fundamentally avoids safety hazards caused by hydrogen leakage.
With a compact, lightweight and rationally arranged overall structure, it greatly reduces on-site installation difficulty and fits narrow pipeline spaces in equipment rooms. In addition, the neat and simplified structure enables easy disassembly and assembly. Routine maintenance, fault inspection and spare parts replacement do not involve complicated procedures, which can significantly cut maintenance time and reduce maintenance costs and downtime losses of power plant hydrogen systems.
Material & Mechanical Performance
Fabricated elaborately from high-quality special alloy materials, the 80FWJ1.6P hydrogen bellows globe valve features high valve body strength and good structural stability, together with excellent corrosion resistance, high-temperature resistance and anti-aging properties. It can effectively resist erosion from hydrogen medium, fluctuations of ambient temperature and humidity, and losses induced by pipeline pressure variations. Capable of stable continuous long-term operation under harsh complex industrial conditions in power plants, it has remarkable resistance to pressure shock and medium erosion, with a service life far longer than that of conventional ordinary valves.
The standardized flange connection of the valve ensures precise butt joint and high sealing fitness. Firm and reliable pipeline connections prevent loosening and leakage during operation, guaranteeing the tightness and integrity of hydrogen transmission pipelines.
Application Function & Operational Value
During the operation of power plant hydrogen systems, the valve achieves precise on-off control of the medium with flexible and reliable switching action and tight shut-off. It can cooperate with various operational scenarios including unit start-up and shutdown, system maintenance and pipeline isolation to stably manage the flow status of hydrogen medium.
Benefiting from excellent sealing performance, reliable pressure-bearing capacity, convenient installation and maintenance, and strong environmental adaptability, the 80FWJ1.6P hydrogen bellows globe valve effectively safeguards the operational stability and safety of generator hydrogen cooling systems, preventing safety risks such as medium leakage and pipeline failure. It serves as an indispensable key control valve for hydrogen piping systems in thermal power plants.
