Atex Speed Switch in KSA – SVA-200 for Air Pressure Engine Shutdown Control

In the demanding industrial and transport environments across KSA, ensuring safe and reliable diesel engine operation is essential. The Atex Speed Switch SVA-200 is specifically designed to control air shutoff valves using an air-powered solenoid, providing dependable overspeed shutdown in hazardous areas. Whether you’re managing oilfield trucks, mobile compressors, or heavy-duty vehicles, this Atex speed switch in KSA is the ideal solution for systems that rely on air pressure braking and automatic safety response.

Ex Proof Speed Switch – Engineered for Safety and Performance

The SVA-200 features a 24V air pressure solenoid, powered to open, and directly integrates into diesel engine overspeed protection systems. It controls airflow to air intake shutoff valves, ensuring that the engine receives clean air under normal conditions—and shuts off safely when an overspeed signal is detected.

Key features:

• Powered by 24V signal, ideal for truck applications

• Opens airflow to valves during normal engine operation

• Automatically closes airflow on loss of signal, ensuring failsafe shutdown

Explosion Proof Speed Switch – Compatible with Revguard 2 Systems

The SVA-200 is fully compatible with speed monitoring system. When an overspeed is detected, the  unit stops sending the 24V signal, prompting the SVA-200 solenoid to cut off air supply, activating the connected valve for shutdown.

This speed switch works seamlessly with:

• MPX valves

• PVX valves

• PVA valves

It helps create a fully automated safety loop, eliminating the need for manual intervention during high-risk overspeed events.

Intrinsically Safe Speed Switch System Integration

While not Ex i certified on its own, the SVA-200 works in conjunction with flameproof and intrinsically safe systems. It serves as the control actuator in shutdown chains, often used in combination with IS-rated valves, controllers, or zone-rated safety systems.
