Knife Gate Valve with Two Plates

Stafsjö’s knife gate valve D2G is a bi-directional tight valve with full bore. The valve is equipped with two hard chromed gates that works towards each other in the bore, which gives an extremely fast operation. This shut-off performance along with its flow characteristics makes it suitable for contaminated media or reject handling. The valve should be mounted only in a vertical pipe line.
