Material | Cast Iron |
Media | Water |
End Connection | Flanged |
Design Type | ball type |
Model | B-01 |
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 of 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.

The control application in pumping systems attracted Normex to come out with control Valves i.e. Butterfly Valves. The Normex Butterfly Valve superseded the Gate Valve, Ball Valve and Globe Valve in most spheres of applications. Gas tight sealing with excellent control characteristics and uni directional flow has qualified Normex Valves by most of the industries. The centrally mounted disc, shafts and bearings has minimised head loss. It’s low weight and compact design has achieved acceptability in industries like Chemical and Petrochemicals, Watertreatment, Agriculture and many • Excellent flow control in quarter turn operation |
