Product Description

Pacbrake's PH5 I PowerHalt Valves are an electronically controlled emergency engine shut down system which forces engine shut down by blocking an engine’s air intake path.

It is available in an automatic engine speed sensing model where shutdown occurs if engine speed exceeds a pre-set speed (or by manual override).

Alternatively, a manual activation-only configuration is available where an operator (or external input) will activate emergency engine shut-down.
