Angular control valve

Angular control valve is a kind of control valve with top guiding structure. It has the advantages of compact body structure, small pressure drop loss, large flow rate, wide adjustable range, small flow resistance and high accuracy of flow curve. It is especially suitable for the regulation of high viscosity, suspended substance and granular fluid. It can avoid coking, bonding and blockage, and is convenient for self-cleaning and cleaning. The control valve is equipped with a multi-spring pneumatic film actuator, which has a firm structure, large output moment and long service life. It is suitable for petroleum, chemical industry, electric power, metallurgy, shipbuilding, papermaking, biopharmaceuticals, food industry systems, etc.
