This Ball-type non-return valves is designed specially for lower pressure contexts 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 small irrigation systems, Applications are domestic pumping, Low rise building pumping. The working pressure is 6 bar. Features innovative design, Focused to eliminate all constraints of conventional one and offer optimum performanceinternals engineered to achieve a specific purpose that laminar flow is not disturbed to a large extent. Very low pressure drop acros the valve which reduces pump, Saves energy cycle time durationopening & closing mechanism is by way to free flowing rubber coated ball hence eliminated hing, Pin, Disc failure. Maintenance free, In case required open top cover. You don't have to remove valve from pipe line, Very low down, Time. Same this valve can serve in extensive variety of applications as It has the potential to be supplied with rubber or frp lining especially for corrosive and errosive applications. Vertical or horizontal installation is easily possiblematerial used is of grade fg 260 having higher tensile strength 26 n/mm2 dimensions can be provided upon request dimensions of the valve mm size a 2540506580100h100135165200244284w90125148190232275
