The two sealing faces of the parallel gate valves are perpendicular to the pipe axis, that is, the parallel gate valve's sealing faces are parallel to each other.
Features for parallel gate valve:
1. It adopts floating valve seat, two-way opening and closing, reliable sealing and flexible opening and closing.
2. The gates are provided with guide strips for precise guiding, while the sealing surfaces are spray-welded with hard alloys to resist erosion.
3. The valve body has high bearing capacity, and the channel is straight-through. When fully open, it is similar to the straight pipe of the ram and the flow tube is small. The valve stem adopts composite packing and multiple sealing, which makes the sealing reliable and the friction is small.
