Details
The pneumatic film regulating angle valve adopts a top-guiding structure and is equipped with a multi-spring actuator. It has the advantages of compact structure, light weight, sensitive action, S streamlined fluid channel, small pressure loss, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly. It is widely used to precisely control the process parameters of gas, liquid and other media such as pressure, flow temperature and liquid level to maintain a given value. It is especially suitable for the adjustment of high viscosity fluids containing suspended solids and granular substances with small allowable leakage and small pressure difference between the front and back of the valve. It can avoid coking, clogging, and is convenient for self-cleaning and cleaning.
