Relief Valve
- A pressure relief valve(s) is (are) installed in the final discharge line and set to
approximately 120-125% of the unit
’s full load operating pressure for protection against over pressure.
Periodic checks should be made to ensure its (their) operation.
The relief valve should be tested for proper operation at least once every year. To test the relief valve,
raise the system operating pressure to 75% of the relief valve set pressure and manually open the valve
with the hand lever. Hold the valve open for a few seconds and allow it to snap shut.
When the relief valve opens, a stream of high velocity air is released, resulting
in a high noise level and possible discharge of accumulated dirt or other debris.
Always wear eye and ear protection and stand clear of the discharge port when
testing the relief valve to prevent injury.
Never paint, lubricate or alter a relief valve. Do not plug vent or restrict
discharge.
