Pneumatic V-Adjustable Ball Valve | Electric Eccentric V-Adjustable Ball Valve
ZRV type V-adjustable ball valve
ZRV type V-adjutment ball valve, a disk with V type slot, which produces sheer force with hard seal seat relative rotation to shut fiber to avoid jamming. It realizes to adjust pressure, flow, temperature, liquid level, and another parameter. It has flowability, high adjustment precision, large adjustment, good sealing, lightweight and other features. It can be used in most situations except small size, angular, three-way connection. It is best to produce instead of importing product, especially applicants to adjust mud and including fiber medium and including micron solid suspended matter. It is widely used in papermaking, sugaring, petroleum, chemical, metal, and other industry automatic control system.
