The AMOT Model 2180 diaphragm gas valves will shut off the fuel gas and vent the manifold when used on an internal combustion engine. Normal application of this model is for shutting down a gas engine in the event of a dangerous condition such as high jacket water temperature, low lubrication oil pressure, excessive vibration, high gas discharge temperature etc.
When pressure is applied to the diaphragm, the vent port closes and the main port and the main port opens to admit fuel gas to the engine. When the diaphragm pressure is released, a spring closes the main ports and the large vent port vents the engine intake manifold causing quick shutdown.
The valves are used in combination with a complete AMOT control system using AMOT sensors for monitoring the condition of the engine.
Typical applications –
- Gas shut off valve
- Gas engine fuel shut off valve
- Gas turbine fuel shut off valve
- Air starting valve
Key benefits –
- Compact design
- Easy low cost installation – valve factory set, no adjustments required
- Simple. low cost maintenance
