Shouldered end butterfly valves are available for reticulation of air and water. If the butterfly valve has a top flange manufactured to ISO5211 then a gear, pneumatic or electric actuator can be mounted directly on it.
Choices for seat materials are NBR, EPDM, Viton, PTFE, polyurethane or metal. This can be selected by fluid compatibility and seat tightness required on closing. Certain butterfly valves carry the WaterMark symbol for use in water supply systems. We resell a variety of Ball Valves from John Valves Manifacturer. John Valves Brand is Australia’s leading valve supplier since 1896.
