Fluorine lined pneumatic control valve

ZJHPF46-16CFluorine lined pneumatic control valveIntroduction

The multi spring actuator developed by Jiangsu Jingmai Automation Instrument adopts a top guide structure and is equipped with a compact structure, light weight, sensitive action, S-shaped fluid channel, small 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, and 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.

ZJHPF46-16CFluorine lined pneumatic control valvePerformance characteristics

The 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.

Feature 1: Corrosion resistance: The valve body cavity, valve core, valve seat, and valve stem are all lined with F46 with a thickness of 2.5-3mm, which can resist acid, alkali, and strong corrosion.

2. Good sealing performance: The corrugated tube and packing made of polytetrafluoroethylene material are double sealed to ensure no leakage.

3. Small leakage: Due to the soft seal of the valve core and seat, the leakage is lower than the standard.

4. Adopting a compact multi spring actuator, it has a small volume, light weight, and high adjustment accuracy.

5. Good regulation function, manifested in ① flow characteristics; ② Adjustable ratio R; ③ Small opening working performance; ④ Flow coefficient; ⑤ Adjust the speed.
