-   0.123 kg
-   Listed for four HPCU and TB applications

## 🔌 Function

Opens at its set pressure to relieve the circuit, protecting the system and its components from over-pressure damage.

## ⚠️ Common Signs of Failure

-   Valve venting in normal operation when it should stay shut
-   System pressure climbing above normal with no relief
-   Weeping or seeping from the valve seat between operations
-   Valve found seized, corroded or fouled with debris on removal
-   Seat or spring damaged so the valve no longer reseats cleanly

## 🛠️ Service Notes

-   This is a protective device - prove it operates at the correct pressure rather than assuming it works, and never blank, plug or adjust one to cure a symptom
-   Depressurise the circuit fully before disturbing the valve
-   If it has been relieving in service, find what raised the pressure before fitting a new valve
