CHECK VALVES
Ball Check Valves, Threaded Ball Check Valves, Manufacturer, Pune, India
 
This Ball Check Valves is designed specially for lower pressure applications where the pipes are threaded. The working principal and features are as model B-01 giving all the advantages of the Ball Type design.

The typical applications are domestic pumping, low rise building pumping, small irrigation systems. The working pressure is 6 bar.

CHECK VALVE - BALL TYPE & CONVENTIONALLLY USED FLAP TYPE
Normex Ball type B-01 Conventional Flap type
Innovative design, focused to eliminate all constraints of conventional one and offer optimum performance Conventional design carries lot of constraints.
Internals designed in such a way that laminar flow is not disturbed to a large extent. Turbulance is generated in fluid flow due to design limitations.
Very low pressure drop acros the valve which saves energy, reduces pump cycle time duration Comparatively high pressure losses, requires more energy increases pump cycle time duration.
Opening & closing mechanism is by way to free flowing rubber coated ball hence eliminated hing-pin-disc failure. Opening & closing mechanism involves hing-pin-disc calls for frequent maintenance.
Maintenance free - in case required open top cover. No need to remove valve from pipe line - very low down-time. For maintenance, valve is required to remove from pipe.
Longer down time.
Same valve can be used for wide range of applications as it can be supplied with rubber or FRP lining especially for corrosive and errosive applications. No such possibility. For these applications special metallurgy required to be used which results in paying high cost for the valve.
Vertical or horizontal installation is easily possible Installation recommended for horizontal position.
Material used is of grade FG 260 having higher tensile strength
(26 N/mm2)
Material recommended is FG 200 having lower tensile strength (20 N/mm2)
