During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height is relatively small. Sensitive action, good sealing performance; Open and close quickly. The overall structure: simple and compact, beautiful shape, low cost for throttling compared to regulating valve. Long service life and high reliability.
Application Scenario: The throttle stop valve is generally used on the pipelines where the flow resistance requirements are not strict and the regulatory flow requirements are not high. For example, a high-temperature and high-pressure working medium, toxic and harmful dangerous liquids, the
closure of closure must ensure long-term sealing, leakage and inaccurate regulating flow. Such as the application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry and other fields.

The Insulation Jacket Ball Valve is specially designed for pipeline systems that require maintaining the temperature of the medium. It is made of high-quality stainless steel or carbon steel and combines with precise processing technology to ensure reliable sealing and smooth control under high-temperature and high-pressure conditions. The valve body adopts a jacketed insulation structure and can be filled with steam or heat transfer oil, effectively reducing heat loss. It is suitable for high-temperature fluid transportation systems in industries such as chemical, petroleum, heat supply, and pharmaceuticals. The structure is compact, the opening and closing is rapid, the sealing performance is excellent, and it is an ideal control valve for high-temperature fluid pipelines.
RAYS Top Entry Cryogenic Trunnion Mounted Ball Valve is a type of valve widely used in cryogenic piping systems, especially suitable for the on/off control of cryogenic liquid or gas media such as liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid hydrogen, and liquid oxygen. Its design features include a top-entry valve body structure for easy online maintenance, an extended bonnet design to prevent condensed water from flowing into the insulation layer, a live-loaded sealing structure design for the valve stem, and a special design of the valve seat assembly.
The Side Entry Cryogenic Floating Ball Valve is specially designed for deep cryogenic media (such as LNG, liquid nitrogen, liquid oxygen, etc.) applications. It adopts a unique side-mounted structure to ensure stable operation in extreme low-temperature environments below -196°C~+150°C. The valve body is made of high-quality stainless steel or special alloy materials, combined with precise processing techniques, achieving zero leakage and long service life under ultra-low temperature conditions. It is widely used in liquefied natural gas, air separation equipment, chemical and energy fields, and is a reliable choice for fluid control in harsh conditions.
