Stop Check Valve

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.

An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ for differential pressure control devices. The valve opens or closes when the differential pressure increases.

The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
