ZSRV Type Pneumatic V-Adjustable Ball Valve

ZSRV Type Pneumatic V-Adjustable Ball Valve disk with V type slot, which produce shear force with hard seal seat relative rotation to shut fiber to avoid jamming. It realizes to adjust pressure, flow, temperature, liquid level and other parameter. It has flow ability, high adjustment precision , large adjustment, good sealing, light weight and other feature. It can be used in mostly situation except small size, angular, three way connection. It is best produce instead of importing product, especially applicant to adjust mud and including fiber medium and including micron solid suspended matter . It is widely used in paper making, sugaring , petroleum , chemical, metal and other industry automatic control system.
