Gate Valve Flexible Wedge Gate Valve
- Gate valves are used for on-off service.
- Gate valves are straight-through flow valves which provide positive shutoff with minimal pressure drop (Low flow resistance coefficient) and flow turbulence.
- Large size valves with short end to end are available.
- Overcome the thermal expansion problems due to the increased temperature with applying the flexible wedge disk or parallel slidedisk for high temperature conditions.
- Gate valve installations should always be made with consideration for the potential of bonnet over-pressurization caused by fluids which may become entrapped in the bonnet of a closed valve. Where this possibility exists, it is the user’s responsibility to insure that proper venting is installed.
- Excellent performance of open/close operations and fluid control capabilities.
- Gate valves may be installed without consideration for the direction of flow, they are not recommended for use in a partially open, throtling position which are caues for erosion, noise and excessive wear.
