AMOT 4261D Butterfly Valves help prevent diesel engine runaway, a dangerous conditions that can injure personnel and cause severe damage to equipment every year. A diesel engine will runaway and self destruct on hydrocarbon vapors, even if the engine’s primary source of fuel is taken away. An air intake shut-off valve is a must for diesel engines which have even a possibility of encountering hydrocarbon vapors. The 4261D Air Intake Shut-off Valves from AMOT use the best available technology to shut down a runaway diesel by closing off engine intake air.
Features
- Corrosion resistant, anodized aluminum and stainless steel construction
- Use as a stand alone or complete runaway shut down system
- Remote reset capability
- Manual, pneumatic, electric or hydro mechanical actuation
