Technical Support

Troubleshooting the Magnetic Speed Sensor for PowerHalt Shut-Off Valves

Jason will be guiding you through troubleshooting the magnetic speed sensor included with your PowerHalt Air Intake Emergency Shut-Off Valve by Pacbrake.


Is this application operated offshore or on ground?

Offshore applications may have specific regulations for your equipment. Corrosion is a concern for offshore applications so PowerHalt valves are all corrosion tested to ASTM B117 96Hrs Salt-Fog to ensure product longevity.

Can manual reset be achieved easily and without placing workers at risk?

Frequent safety checks may prove cumbersome when manually resetting the valve if it is difficult to access. Our automatic reset option is best suited to these applications. Routing of the switch or pull cable is an important consideration to make. Pull cables are a great low cost option if your application and regulations allow.

Does your system have a compressed air source?

Pneumatically actuated valves require an air source of 60 psig (minimum) to 145 psig (maximum).

Does your engine require dual shut-off valves? (This changes the specification for control)

Large V-engines may require two or more shut-off valves. The automatic reset option is recommended to prevent incidents where only one valve is reopened after a shutdown, preventing engine damage.

Does your application require auxiliary/multiple sources for activation in case of emergency?

The PowerHalt PH3 series can incorporate multiple auxiliary inputs from external sources for activation of the shut off valve in the event of an emergency. Ideal for secondary emergency monitoring systems as well as multiple locations for manual override input
