Overview of Pneumatic Thin Film Single Seat Regulating Valve

ZJHPThe new series pneumatic thin film straight through single seat regulating valve adopts a top guide structure and is equipped with a multi spring actuator. It has a compact structure, light weight, sensitive action, and a filling channelSThe advantages include streamlined design, 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. Especially suitable for working environments where the pressure difference between the front and rear of the valve is not large and the leakage is allowed to be small.

There are various types of products in this series, including standard type, adjustable cutting type, corrugated pipe sealing type, jacket insulation type, etc. The nominal pressure rating of the product includesPN10、16、40、64Valve body diameter rangeDN20~200Applicable fluid temperature-200℃~560℃Multiple levels within the scope. Leakage standards includeIVGrade orVIGrade. The flow characteristics are linear or equal percentage. A variety of varieties and specifications are available for selection.
