Butterfly Valves___________________________________________________
 
Design Features

Butterfly Valves are designed and manufactured to have optimal mix of structural stability, flow efficiency and effective seating coupled with advantage of light weight,  compact and ease of operation. Only a quarter turn is needed to fully open or close the valves.

The valves are provided with integrally moulded elastomer body liner to provide perfect seating and complete isolation of body material from media to prevent it from any corrosive and abrasive impact of fluid. The body liner material can be provided to suit specific fluid service for long maintenance free life.

The valves are easy to install in any position between horizontal to vertical piping. No gaskets are required as the body liner effect seal between the valve body and the mating pipe flanges.

Standard wafer valves are available from 2” -24” and require only one set of mating flanges, as otherwise required for flanged valves. They also required only one set of studs and nuts instead of two sets required for flanged valves. They thus save installation time and cost.

Lugged type valves are also available in all sizes up to 24” as per requirement.Flanged type valves are available for sizes beyond 350mm (14”) N.B. Advance Butterfly Valves are maintenance free ‘FIT & FORGET’ valves.
