Two Safety Relief Valves on a Manifold

This 3D model shows a typical setup of two safety relief valves on a single manifold. This type of setup is often employed where a catastrophic failure of machinery downstream would have significant financial impact, or, loss of life.

The second Safety Relief Valve (SRV) adds a layer of safety as normally only one SRV must operate in order to relieve the highest possible pressure accumulation rate.
