1Overview
ZJHPcompactPneumatic thin film single seat regulating valveAdopting a top guide structure and equipped with multiple spring actuators.

It has a compact structure, light weight, sensitive movement, and fluid channelsSThe 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 process parameters such as pressure, flow rate, and liquid level maintenance of gases, liquids, and other media At the given value.

Especially suitable for working environments where small leakage is allowed and the pressure difference before and after the valve is not significant.
   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 includesPN16、40、64; nominal diameter rangeDN20～350.

Applicable liquid temperature is determined by-200℃to+560℃Multiple levels within the scope. Leakage standards includeⅣGrade orⅥThe flow characteristics are linear or equal percentage. There are a variety of character specifications to choose from.
