4110 Hydro-Mechanical Overspeed Sensing Valve

The Model 4110 Overspeed Sensing Valve provides mechanical overspeed protection for engines and rotating equipment. Its flyweight speed sensor vents a pneumatic or hydraulic signal at a preset RPM through an integrated two-way valve.

As part of a full mechanical shutdown system, the 4110 is often installed alongside AMOT’s diesel engine safety parts, including shutdown valves and air-intake devices used to interrupt combustion air during overspeed events. The 4110 may also be deployed in systems that include AMOT engine speed switches, providing an additional electronic or redundant trip source when dual-mode overspeed detection is required.

Features/Benefits

• Dependable protection from overspeed for engines and rotating equipment - reduces risk of engine damage and injury to personnel

• Available settings from 800 - 4200 RPM in several mounting arrangements - adapts to most popular engine makes and models with ease. Trip setting is field adjustable.

• Top mounted tachometer drive - can be mounted ‘in-line’ with existing tachometer cable and tachometer

• May be mounted in any position

• Factory packed bearings - extends life of equipment

• Gulfproofed (anodized aluminum) construction - proven corrosion resistance even in offshore environments

• No electricity required, fail safe - low cost and simple installation

• Compatible with other AMOT safety control sensors - AMOT provides sole source responsibility for shut down system
