V101 (Wafer) / V102 (Lug) Series Proval Soft Seat Butterfly Valves Butterfly valves, since their invention in 1960’s became one of the most demanded flow control elements in industrial and domestic flow control applications due to their light weight, low pressure loss, 100% leak free operation, easy and economic automation capabilities. Beside the soft seat applications, development of PTFE seats and metal seats of double eccentric high performance valves today,butterfly valves are used from basic water applications to industrial applications and highly corrosive severe service applications Butterfly valves have wide range of applications in water, sea water, steel, food, paper, chemical, petrochemical and all HVAC and general industrial flow process controls. Superiorities of New Design Proval V101 Butterfly Valves • Flow indication marked, ISO standard valve rotating shaft • Easy removable, anti blow-out plate • According to ISO 5211 direct mount ISO pad • Tag plate with all valve material and useage data incuding valve Seriesal number • Upper stem bushing • Long neck for easy insulation • PTFE / Bronzee bushing provides low torque and longer seat life by centering the disc and avoids leakage from stem due to non-centric rotation • EN1092 PN10, PN16 ANSI 125/150 and BS10 Table-D, Table-E suitable flange holes • Integral o-ring system on seat avoid the leakage from stem • 2 Pc shaft construction disc provides higher flow rates (kv) and lower pressure loss in pipeline. • Wide range of seat solutions for all industrial applications • Special groove on body provides less torque figures in operation and improves the life cycle of seat • 4 flange locating holes for easy allignment of valve during installation. • O-ring to ensure 100% leak free operation • PTFE / Bronzee bushing provides low torque and longer seat life by centering the disc and avoids leakage from stem due to non-centric rotation • Easy removable lower cap provides easy dismantling of the valve to replace any defected parts on maintenance
