Pneumatic Control Valve ZJHM-25C Pneumatic Thin Film Sleeve Control Valve DN20

Description :

　　1. Product Overview

　　The ZJHM-25C pneumatic diaphragm regulating valve consists of a multi spring pneumatic actuator and a regulating valve body. Adopting a top guide structure, it has the advantages of compact structure, light weight, sensitive action, S-shaped fluid channel, low pressure drop loss, large valve capacity, flow characteristics, and easy disassembly and assembly. Widely used to control process parameters of gases, liquids, and other media to maintain pressure, flow rate, temperature, and liquid level at given values. Especially suitable for situations where the allowable leakage is small and the pressure difference before and after the valve is not significant.

　　Adopting a balanced valve core structure, the axial unbalanced force is small, allowing for a large pressure difference and good stability.

　　The sleeve has strong interchangeability, easy disassembly and assembly.

　　The all metal valve core structure achieves a soft sealing structure with a leakage level of IV and a leakage level of VI.

　　The valve body is designed according to the principles of fluid mechanics as an equal cross-section low flow resistance channel, with an inherent adjustable ratio of 50 and a 30% increase in rated flow coefficient.

　　The actuator adopts a multi spring structure, reducing the height by 30%. Reduce weight by 30%.
