Bleed valve takes on high-performance
engines
A new industrial bleed air valve is designed to handle high-pressure air at the extreme temperatures that are common in modern, high-performance engines.
Dunlop Aerospace Equipment (DAE) of Coventry, UK has developed and is manufacturing a new industrial bleed air valve The new valve is a butterfly design and allows the flow of air through the unit to be varied across a range, as commanded by the engine management system

High head pumps for wastewater pumping
ABS is introducing a new series of HiLift pumps for high head pumping. The new range offers reliable wastewater pumping from buildings and sites.
It is designed to handle high-pressure air at the extreme temperatures that are common in modern, high-performance engines.
The new DAE valve embodies a "triple-offset" concept that results in a robust, reliable product capable of withstanding the harsh operating conditions specified by many engine manufacturers.
This new design features very low operating torque and minimal leakage rates.
It offers unusually quick release or sealing and can be operated either in a fail-safe open or closed mode to suit safety requirements.
The modular concept of the valve enables scaling to suit different size requirements, while accommodating a wide range of different actuators - electrical, hydraulic or pneumatic.
Mark Johnson, Director of Dunlop Aerospace Equipment, commented: "The new valve incorporates certain design philosophies that we have already proved in aerospace applications.
We believe that it represents a step-change in the design of bleed air valves for industrial engines and an exhaustive programme of high-temperature, endurance testing shows that it will be robust and reliable in operation".
