Introduction:

QB metal seated  cast steel knife gate valve ( QB High Pressure Water Valve )is a new type knife gate valve whose seat is fixed up on the body. The metal seat ring moves ladderlike with body, and moves concavo-convex with seat. QB Knife Gate Valve Manufacture is with O type seat ring is set between the metal seat ring and the seat, and a seat ring is at the joint of the seat and the body.
