1、 Overview of Pneumatic Angle Regulating Valve Products
The pneumatic diaphragm angle regulating valve of Shanghai Yuhu Company adopts a top guide structure, consisting of a multi spring pneumatic diaphragm actuator and an angle regulating valve body. Pneumatic angle regulating valves have the advantages of compact structure, light weight, sensitive action, streamlined fluid channels, low pressure drop loss, large valve capacity, precise flow characteristics, and easy disassembly and assembly. Pneumatic thin film angle regulating valve equipped with electric pneumatic valve positioning or pneumatic valve locator can achieve automatic adjustment and control of the fluid medium in the process pipeline. Pneumatic high-pressure angle regulating valve has the characteristics of small volume, light weight, top guided valve core structure, simple flow path, low resistance, and easy flushing. Pneumatic angle control valves are widely used for precise control of gases, liquids, and other media, with process parameters such as pressure, flow rate, temperature, and liquid level maintained at given values. Pneumatic angle high-pressure regulating valve is particularly suitable for regulating high viscosity, suspended solids and particulate matter with small pressure difference before and after the valve, which allows for small leakage. It can avoid coking and blockage, and is convenient for self-cleaning and cleaning.
