Insulation stop valves are widely used in industries such as petroleum, chemical, metallurgy, and pharmaceuticals to handle high-viscosity media that tend to solidify at normal temperatures. The BJ45W DC jacket insulation stop valve features a thermal insulation jacket between the flanges, with two connection ports on either side of the valve for steam or heat input. This design helps maintain the temperature of the medium, preventing it from crystallizing or solidifying, making it ideal for use in chemical and fertilizer plants. By introducing steam into the jacket, the valve ensures smooth flow and prevents blockages in pipelines.
One of the key advantages of the heat-insulating stop valve is its simple structure, which makes it easy to manufacture and maintain. It also has a short working stroke, allowing for quick opening and closing operations. The sealing performance is excellent, with minimal friction between the sealing surfaces, leading to a longer service life. However, there are some limitations. The fluid resistance is relatively high, requiring more force to operate the valve. Additionally, it is not suitable for media containing particles, high-viscosity substances, or materials that tend to coke easily. Its adjustment capabilities are also limited compared to other types of valves.
In summary, the insulation stop valve is a reliable choice for applications where maintaining the temperature of the transported medium is critical. It offers good performance in terms of sealing and durability, but users should be aware of its limitations when handling certain types of fluids. Proper selection and maintenance can help maximize its efficiency and lifespan in industrial systems.
