    The perfect valve for reject and contaminated media

Knife gate valve D2G

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.

The D2G valve is supplied in stainless steel with hard chromed gates to increase the wear resitance and extend the service life. The valve is also supplied with the retainer ring system on both side of the gate, which protects the PTFE seat upon service and makes it extremely easy to maintain. As standard it is supplied with two double-acting pneumatic cylinders including quick exhaust valves.

The D2G valve is available from DN 100 up to DN 600 (4” to 24”). Further information is available in the product data sheet.
