Double Flanged Butterfly Valve


With a low operating torque these valves have very sturdy and robust design. KBL has successfully carried out Flow Test on large size Butterfly Valves including 2200 mm in its in-house Hydraulic Research Centre at Kirloskarvadi. Another feature which makes KBL butterfly valves competitive in the market is its low life cycle cost and lower maintenance. With centric type pressure up to PN 1.6/Class 250, these valves find wide application in water works, water/effluent/sewage treatment plants and so on.
