- Part of the B Series of easily installed, compact, air intake valves for diesel engine emergency shut down.
The BAE version of the Fluid Power Energy (FPE) B Series of engine air intake closure valves is designed to be installed in the air intake system of a diesel engine, providing an emergency rapid shut down when triggered by a12 or 24 volt signal. This signal may be generated automatically by engine overspeed or any other selected fault conditions and/or applied via a manual emergency stop button.
Once the BAE valve has operated to stop the engine the valve will automatically reset to the open (engine run) position, as soon as the shut down signal is no longer applied.
The low intake air flow restriction through the open valve, makes it generally compatible with the requirements of low emission diesel engines.
Corrosion resistant materials are used where applicable in the construction of the valve. This lightweight and compact valve design, together with the availability of factory fitted hose adaptors selected from a wide range of optional sizes assists in easy installation.
The valve may be fitted to work with either turbocharged or naturally aspirated engines. In the case of turbocharged engines, temperature limitations may restrict the position in which the valve may be installed in the intake system.
Note: FPE also supplies speed switches for incorporation into the emergency shut down control circuit for this type of application. Please contact FPE or your FPE supplier for details.
The FPE B series of intake shut down valves are also available with cable operated manual shut down. Contact FPE or your FPE supplier about this additional safety feature.
Versions of the BAE valve can be selected to operate by either a 12 volt or 24 volt shut down signal. Once the input shut down signal is removed, the valve always automatically resets to the open status.
In standard form, the BAE valve is available complete with formed hose adaptors. Hose adaptors are selected by the customer from a range of standard sizes – see diagram below and data on pages 4 and 5. If there is a requirement for a non-standard adaptor size or other alternative form of the intake pipe connection, such as bolted joint, please pass details of requirement to FPE or your FPE supplier for investigation.
Optionally, the valve can be supplied fitted with an internal microswitch to indicate the open/closed status of the valve.
The valve has a metal to metal seal when closed. It is designed to close with low friction to ensure the long life of the sealing surfaces. The latch-ing/release mechanism is configured to withstand high shock loads without malfunction. The electrical enclosure is designed to code IP66.
The diagram shown covers the main features and basic dimensions of the BAE range, including selection of options and order coding.

To ensure FPE selects the most suitable version of the BAE valve for the customer application the following data is required:
1. Bore size of the intake hose into which the intake valve is to be fitted – refer to section headed “Mechanical Installation.”
2. Whether a 12 volt or 24 volt shut down signal is to be used.
3. Whether a built in microswitch is required.
