ZSRD pneumatic membrane adjustment butterfly valve adopts intelligent control, and can use electric or pneumatic actuator to realize the adjustment of pressure, flow, temperature, liquid level and other parameters. It has the advantages of compact structure, strong function, small size, good sealing, reliable performance, simple supporting and large circulation capacity, especially suitable for occasions where the medium is viscous, containing particles and fibrous properties. At present, the control valve is widely used in industrial automatic control systems in food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and scientific research equipment, electric power and other industries.
