ZXS type new series pneumatic thin film angular single seat regulating valve
Product Description: The ZXS new series pneumatic thin film angular single seat regulating valve adopts a top guide structure and is equipped with a multi spring actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, S-shaped fluid channel, low pressure drop loss, large valve capacity, precise flow characteristics, and easy disassembly and assembly. Widely used for precise control of gas, liquid and other media, process parameters such as pressure, flow rate, temperature, and liquid level are maintained at given values. It is particularly suitable for regulating high viscosity fluids containing suspended solids and particulate matter with small leakage and small pressure difference before the valve, which can avoid coking and blockage, and facilitate self-cleaning and cleaning. This series of products includes various types such as standard type, adjustable cutting type, corrugated pipe sealing type, jacket insulation type, etc. The nominal pressure rating of the product includes PN10, 16, 40, and 64; The valve body diameter range is DN20~200. The applicable fluid temperature ranges from -200 ℃ to+560 ℃, with multiple grades within this range. The leakage standard has IV or VI level. The flow characteristics are linear or equal percentage. A variety of varieties and specifications are available for selection.
Product Features: Top oriented, bottom in and side out, simple flow path, low resistance, and large valve capacity. The adjustable range is large, with an inherent adjustable ratio of 50, and the flow characteristics include straight lines and equal percentages. The actuator adopts a multi spring structure, reducing both height and weight by 30%. The ZXNV bellows sealed regulating valve forms a complete seal for the moving valve stem, blocking fluid leakage. The ZXNJ type regulating valve is equipped with an insulation jacket, which is used in situations where the fluid is prone to crystallization and solidification after cooling, causing blockage.
