Through conduit Knife Gate Valve

FREE-Valve’sthrough conduitknife gate valves are known as slurry gate valves.Itsarebi-directional wafer knife gate valve.It is mainly designed for highly concentrated flow media. With a through going O-port plate,through conduitknife gate valvesprovide a stable and safe shut-off performance without clogging. With double-seat design, it cancontrolflow in both directions.

Features:

1.Two-way sealing with two seal rings on the valve seat,this gate is longer and the bottom extends out of the valve body and requires two packing glands.Thegate discis ground smoothly on both sides to eliminate adhesion and clogging.

2.The gate disc forms aO-port platewhose role is that when the gate opens,medium may flow away completely without any detention,when the gate closes,it may be completely sealed.It can easily cut through the media during on-off operation.

3.When the media are of high concentration, it may also keep the valve seat sealed,as there is no detention area,the bottom of the gate without medium accumulation.
