Overview
VB Valves manufactures the full range of Gate Valves, which are ideal for bi-directional, low friction flow and shut-off as per international standards. Due to the flow characteristics of the wedge to seat design, Gate Valves are always operated in the full close or full open position.
VB Valves offer wide range of sizes in gate valve right from 2 to 24 (DN- 50 to DN -600) and pressure rating ranges from #150 to #2500. Higher pressure rating and bigger sizes can also be provided.
