Butterfly Valves

Butterfly Valves are Fabricated Design with lens Disc. Double eccentric positioning of the disc permits smooth raising and resting of the disc-seal from / on the sealing surface. They have double sealing system on the shafts and special profile of the disc seal for positive, long term tightness with standard seals materials BTV valves may be used in liquid and gaseous service for temperatures up to 150 degree C.
