TPZ SERIES - AIR PRESSURE TO STOP

A range of diesel engine air intake shut down valves which automatically close on engine overspeed or when an air pressure signal is applied. As an optional feature, TPZ valves can also be supplied with fitted cable and handle RTD -100 to also enable manual shutdown.

TPZ valves are available for all popular combinations of air intake pipe sizes and engine ratings up to 149kw (turbocharged) or 179kw (naturally aspirated). The smaller sized TPZ valves can also be supplied with an integral engine air cleaner.

This type of valve may be fitted to either naturally aspirated or turbocharged engines. It should be noted however that for a given valve setting the repeatability of the actual shut down speed has a greater scatter in the case of a turbocharged engine. However, unless for special reasons a precisely repeatable shutdown speed is required, adequate protection from excessive overspeed and potential resulting damage is still achieved.
