Product Description

 

ZDLS type electric angular regulating valve is a product developed for regulating valve under the severe working conditions of high pressure or high pressure difference, serious cavitation, erosion, short life, valve stem easy to break, bushing easy to fall off serious problems. It adopts multi-level throttling form to apportion the pressure difference, reducing cavitation, erosion, torsion flow damage, greatly improve the service life of the regulator, especially used in urea system than ordinary high pressure valve life increased 2-3 times. The valve body is a right Angle shape, the spool is a single guide structure, the valve body flow path is simple, the resistance is small, especially suitable for the adjustment of high viscosity, containing suspended matter and granular medium fluid, can avoid coking, bonding, blocking.
