It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc. to transport high viscosity media that solidify at room temperature. The insulation jacket of BJ45W DC jacket insulation globe valve is welded between the two flanges of the valve, and there are two connection ports for the insulation jacket on the side and bottom of the valve. DC insulation globe valve is particularly suitable for pipelines in the chemical and fertilizer industries, and the inclusion of steam in the jacket can prevent the crystallization of the medium. Insulated globe valves are widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc.
The API 6A High Pressure Slab Gate Valve is specially designed for high-pressure pipeline systems in industries such as petroleum, natural gas, and chemical engineering. It features a valve body made of high-quality alloy steel, which is precisely machined and rigorously tested to ensure reliable performance under high pressure, high temperature, and corrosive medium conditions. The unique flat gate plate design enables two-way sealing, allowing for flexible opening and closing with low flow resistance. It is an ideal choice for long-distance pipelines, refining and chemical plants, and high-pressure fluid control systems.
The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
