## ⚙️ Key Features

-   0.887 kg
-   Supersedes 3953945, formerly catalogued as a regulator
-   60 applications across four engine series

## 🔌 Function

Controls flow or pressure in its circuit, opening and closing to hold the system at the value it is set for.

## ⚠️ Common Signs of Failure

-   Pressure too high, too low or wandering in service
-   Valve heard to chatter, buzz or hunt

-   Weeping around the valve body or its joints
-   Seat or seal found pitted, scored or fouled with debris
