ABO - Model Series 200 -Knife Gate Valves

The most common of the so-called knife gate valves. A unidirectional wafer type valve ideal for installations handling liquids which contain suspended solids and waste water (mining, chemical treatment, water treatment, etc.). These valves are especially useful in facilities with limited space, thanks to their small size and light weight. Long-life service of the product is secured as a circular blade bevel prevents excessive wear and clogging (leakage). The valve is reinforced with oversize top and bottom ends to ensure proper sealing. Beveled knife hacks away fibrous particles, moving them towards a self-cleaning bottom area and rinsing them out of the saddle. The valve can be manufactured with bonnets which provide for total water tightness towards the outside environment, thereby reducing the maintenance of the packing gland.
