Product Details
●Overview
ZJHSThe small-sized 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, streamlined fluid channel, low pressure drop loss, large valve capacity, precise flow characteristics, and easy disassembly and assembly. Widely used for precise control of process parameters such as pressure, flow rate, temperature, and liquid level in gases, liquids, and other media to maintain them 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 product comes in various varieties such as standard type, adjustable cutting type, corrugated pipe sealing type, jacket insulation type, etc. The nominal pressure rating of the product includes PN16, 40, and 64; The valve body diameter range is DN20-200. Suitable fluid temperatures range from -200 ℃ to various levels. 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.
