Hanwel supplies a wide range of centric and eccentric butterfly valves. Our butterfly valves are available with multiple seals and in different designs. We are therefore always able to offer the right solution to specific challenges. Our specialists will be happy to visit you to select a suitable model with you.
All butterfly valves are as a standard available in three versions.
A wafer type, or inter-clampable butterfly valve is mounted between two flanges and is fitted with four eyes to centre the valve. This version cannot be used as an end valve.
A lug-type butterfly valve has eyes with threaded holes according to the desired pitch circle. This valve can be attached directly to a flange and can be used as an end valve.
The flanged version is fitted with two flanges according to the desired pitch circle. This version can therefore be used as an end valve.
