Air shut-off valve protects diesel engines

AMOT product story

The control panel monitors engine speed and sends a shut-down demand to the valve if it exceeds a set limit.
AMOT has released the SpeedTrap Model 4261 ATEX-approved, electric 250mm hazardous area emergency engine air shut-off valve.
The valve is designed to protect bigger diesel engines from dangerous and damaging runaways when they burn hydrocarbon vapours or other combustibles, even after their fuel source has been closed.
ATEX-approved to EX II 3 G EExn IIC T4, zone II, the valve is fully controlled by a custom electronic control module preventing the solenoid from generating excessive surface temperature.
The valve retains all the features of the standard Model 4261 but has also been mechanically modified to comply with ATEX.
Solid state sensing and control boost the system's reliability.
SpeedTrap valves can be used stand-alone or in complete runaway shut-down systems.
They have a compact design with easy low-cost installation and a remote reset facility for more flexible control.
The control panel monitors engine speed and sends a shut-down demand to the valve if it exceeds a set limit.
A valve position feedback signal confirms valve actuation.
First designed to match the size and power of a 16V cylinder engine required for offshore power generation, the 250mm diameter valve is ideal for oil field and on/offshore sites and a range of other demanding applications.
