Principal: Ball Type Check Valves (NRV) B-01 was the first of the valve at Normex with unique design and technology for the first time in India. A very simple and robust design with no mechanism involved. The heart ofб═ valve is rubber coated ball. The mechanism hinge-pin-disc used in conventional check valves is eliminated and Normex has put in this rubber coated ball to arrest flow media in return condition. As the pump starts, the ball moves out totally from the flow path when the pumping is on giving a full bore maximum flow/discharge with minimum head losses. (Fig. A). As the pump stops, the ball rolls back and seats perfectly on the rounded valves seat ensuring totally leak proof sealing.(Fig. B) Salient Features: Lowest possible pressure drop across the valves. 100% leak proof sealing years over years. Non-clogging and self cleaning as ball rotates during operation. Virtually no wear and tear, no maintenance and longer service life. Higher solid handling capacity due to full bore and straight internal path. Lower head loss-high discharge, reduced pumping time-All leading to Energy Saving. Applications: Clean water, Raw water, Sewage, Slurry, Waste water, Viscous liquids etc. Used in industries like: Fire fighting, Plumbing, Water distribution, Water/Sewage treatment, Irrigation/agriculture, Sewage plants, Steel mills, Power stations, Chemical/process industries, HVAC, Sugar/food industry, Breweries, Mining and many more.

No rotary action means no need to build clearence (leckage) into the valve. Double flaps ensure the seal is never lost throughtout filling and emptying of the valve. Full throught opening eliminates bridging, jamming and material build up. Seat and flapper can be reground several times to bring them back to original condition and performance. Housing does not come in contact with material allowing it to last much longer life.

We are offering oswal check valves are heavy duty, bolted cover, renewable seat ring, and body mounted disc swing type. Valves are straight through flow which works automatically. They are opened by the force of velocity pressure and closed by the force of gravity and back pressure. The valves are single direction flow and restrains flow in opposite direction. Distortion, wear and noisy operation of the valve can be avoided by selecting the size of the valve on the basis of flow conditions. Swing check valves are best suited for moderate velocity operations. Swing check valves are normally designed for horizontal installations. It can be installed in vertical direction with flow in upward under the disc. There is no tendency for seat to gall because the disc meets flat surface without rubbing upon contact. The most advanced design features provides the ultimate in dependable, economic flow control. They are available in wide range of sizes and weights. Flow directions are marked as cast on the body for ease of installation. Swing check valves are adequate for all service media. Valves can also be supplied with counter weights and dash pot arrangement depending upon the condition and request.
