Pound-grade gate valve structural features
Low fluid resistance. The medium channel inside the gate valve body is straight-through, and the medium flows through the channel without changing direction, so the flow resistance is small.
More labor-saving for opening and closing. The movement direction of the gate plate is perpendicular during opening and closing, so it is more labor-saving.
The medium flow direction is generally not restricted. The medium can flow through the gate valve in any direction, and the purpose of connection or cutoff can be achieved.
