Air Intake Shutoff Valves

Air intake shutoff valves (often referred to as AISV, ASOV or emergency shutdown valves, ESD) and systems provide emergency overspeed shutdown protection for diesel engines and are the most effective way of preventing a runaway situation. The valves completely block the engine air intake system, cutting off an uncontrolled external fuel source and the air required to keep the engine running.  Our air intake shutoff product offerings include AMOT, Chalwyn, Rigsaver and Roda Deaco brands.

Flameproof Alternators

Standard automotive type alternators are a continuous potential source of ignition when operated in hazardous atmospheres where combustible concentrations of gas, vapors, or dust may exist. AMOT offers a range of ATEX Group I mining and Group II hazardous area approved flameproof alternators which mount on diesel engines as direct replacements for standard alternators.

Spark Arrestors

Chalwyn spark arrestors are designed to prevent the risk of fire due to spark emissions from diesel engine exhaust systems. They are designed for use in marine, oil & gas, refineries, mining, forestry and other hazardous area applications. We offer a range of spark arrestors that meet the requirements of ASTM F2876-10 are ATEX certified in accordance to EN 1834-1/2/3:2000, EN 14363:2000, and meet ASTM F2876-10.

Temperature Control Valves

AMOT temperature control valves, also known as temperature regulators, include: thermostatic internally-sensed temperature control, externally-sensed temperature control, and electrically or pneumatically actuated temperature control valves.  Actuated 3-way temperature control valves are used for tighter temperature control, remote temperature sensing and low pressure drop applications. For help selecting the right temperature control valve, view our selection guide.

Fuel Shutoff / Air Start Valves

We have a line of rugged, compact fast acting valves for use in gas fuel shutoff and engine air start applications. The fail-safe pilot pressure operated 2-way and 2-way vented valves have a wide range of operating capacities and pressures. They can operate in a variety of environments and include NACE compliant and hazardous area approved models.

Fuel Metering Valves

High performance gas fuel metering valve designed for use with industrial and aeroderivative gas turbines. The balanced rotary valve features fast operation with very high precision and large turn down ratio for reliable and efficient control.

Bearing Condition Monitoring

The XTS-W Bearing Condition Monitor provides ‘real-time’ data on crank train bearing condition. It displays the rate of degradation, bearing wear, water-in-oil content, and shaft line earth monitor to fully protect the crank train bearings. The XTS-W provides ‘real time’ information allowing the user to take appropriate corrective action thus avoiding consequential damage, costly unplanned repairs and loss of revenue.
