ZXM series pneumatic diaphragm regulating valve (DN350)

The working principle of the pneumatic diaphragm regulating valve is to control the position of the valve disc by adjusting the amount of air entering the pneumatic diaphragm actuator, thereby achieving fluid flow control. The pneumatic diaphragm actuator consists of a diaphragm, a spring, and a piston. When the input air pressure acts on the diaphragm, the diaphragm deforms, driving the piston to move and change the position of the valve disc, achieving flow regulation. The valve disc component of the pneumatic diaphragm single seat regulating valve is precision machined, which can achieve high-precision flow regulation. The pneumatic diaphragm single seat regulating valve is made of high-quality materials, with high corrosion resistance and wear resistance, and long service life. Pneumatic thin film single seat regulating valves are widely used in industrial fields such as petroleum, chemical, power, metallurgy, and environmental protection to control fluid media in various process flows, such as gases, liquids, steam, etc. Especially under harsh working conditions such as high pressure difference, high corrosion, and easy crystallization, the pneumatic thin film single seat regulating valve has good stability and reliability, which can ensure the stable operation of the process flow. £©
