Series 204 | Vatterfly valve extended body

Vatterfly valve extended body

For processes requiring a high conductance, but an optically free passage in the open valve position is not a must. Well suited when a compact system design is required. The extended body ensures that the valve plate does not protrude the body when it is in the open position.This is important when the valve is mounted on a pump.
