Quick Relief Valves

A quick relief valve protects water systems against excessive pressure caused by water hammer. The valve is typically installed on a branch off the main pipeline. It is controlled by a pilot which can be set to the desired relief pressure. If the line pressure reaches this set point the valve quickly opens relieving the excess pressure.

Typical Applications
Quick relief valves are typically installed in water systems subject to potential water hammer to protect the water deliver network. They are commonly used in pressurised irrigation systems.
