The 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, 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. 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, the allowable pressure difference is large, and the stability is good.
• The sleeve has strong interchangeability, easy disassembly and assembly.
• The all metal valve core structure achieves a soft sealing structure with IV level leakage and VI level leakage.
• 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%.
