Intake Safety Valve; Operating And Maintenance Procedure; Inspection Guide - Kohler SFGLD480 Operation & Maintenance Manual

1. INTRODUCTION
This Product Information document establishes the intake safety valve operating and maintenance procedure.
2. OPERATION AND MAINTENANCE
2.1. OPERATION
Safety valves protect people as well as engines in case of explosions in the intake system of gas engines.
They include adequately calibrated inner springs to ensure the valve opens in case of overpressure building up in
the intake manifold and releases the air-fuel gas mixture until the rated pressure is restored in the intake system.
Also, wrapping the valve externally, there are a few plates whose sole object is to extinguish the fire as it catches.
Finally, an O-ring gasket seals the whole unit during the normal operation of the engine

2.2. INSPECTION GUIDE

1. Intake safety valves shall be visually inspected, on a regular basis, during their service life on the engine.
WARNING
2. Due to residual heat, do not touch these valves after an explosion, since otherwise you would expose
yourself to severe injury.
ATTENTION
3. After an explosion, the flame-killing plates must be visually inspected and the valve replaced if said plates
show gaps or any other damage whatsoever.
4. Do not work on the engine when the same is running.
5. Reasons for rejecting a valve during its visual inspection:
- Gaps or incorrect interspace between the flame-killing plates.
- Damage or wear of the plates.
Gas leaking through the valve due to improper seating of the valve disc as a result of a damaged
-
O-ring.
Loose plates, rotating freely, without strain.
