Product Overview:
The ZJHPF series precision small pneumatic thin film single seat fluorine lined 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, 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 process parameters such as gas and liquid media to maintain pressure, flow rate, temperature, and liquid level at given values. Specially used in situations where the leakage is small and the pressure difference before and after the valve is not significant. This series of products includes standard type and adjustable cut-off type. The nominal pressure rating of the product includes PN0.6, 1.0, 1.6, 2.5 class150LB; The nominal diameter range is DN20~300; The operating temperature ranges from -20 ℃ to+200 ℃ in various grades; Leakage level VI, flow characteristics are linear or equal percentage.
The ZJHPF series precision small pneumatic thin film single seat fluorine lined regulating valve is the execution unit in the pneumatic unit combination instrument. After being equipped with an electric gas conversion device, it can also enter the electric unit combination instrument system. It receives signals from the regulating instrument and directly changes the flow rate of the regulated medium (such as liquid, gas, steam, etc.) to maintain the controlled process parameters (such as temperature, pressure, flow rate, etc.) at the given values.
