Wedge valves
Wedge valves make part of pipeline components. In a wedge valve saddles are positioned with a small angle between them, and the gate has a form of a wedge which, when the valve is “closed”, can be inserted well into the space between saddles.
| Type of connection | welding, flanged |

A wedge valve is a highly secure type of stop valves. This article can enable minimum pressure losses during the flow when a pipeline is closed. Its construction reduces noise and vibration and enables slow filling in and slow discharge of a pipeline.
