Guanli Gate Valves OS&Y Sizes: 2" thru 36" Class: 150 thru 1500 Gate valves are ideal for bidirectional, low-friction flow and 100% shut-off. Due to the flow characteristics of the wedge-to-seat design, gate valves should be operated in the full-open or full-close position. Concentrated flow across the seats of a partially opened gate valve risks possible seat damage, therefore throttling is not recommended. Gate valves are utilized in applications where minimum pressure drop is necessary.
