Products
Engine air control valves - Dunlop Equipment manufactures a wide range of solenoid-actuated servo bleed valves which are used to control air flow in the high and low pressure stages of jet engines and prevent the onset of hazardous engine surge conditions. Operating within proven design rules, Dunlop Equipment bleed valves achieve extreme reliability with a typical MTBF of 100,000 hours.
Anti-icing valves - Dunlop Equipment produces anti-icing valves suitable for deicing engine intake nacelles, wings and other airframe structures. These valves are designed for sustained high temperature operation and can be configured in normally open or shut variants. On/off control is achieved via a simple solenoid pilot valve, maximising reliability with minimum costs.
Check and non-return valves - Often operating in very harsh environments, Dunlop Equipment pneumatic check/non return valves provide unidirectional flow and safety shut down functions to a variety of aircraft systems. These valves are designed to provide stable operation under a wide range of temperature and flow conditions.
Pressure reducing valves - Dunlop Equipment has a long heritage in the design of pressure reducing valves. Primarily designed for pneumatic applications, inlet pressures of up to 450 bar can be accommodated. Often operating in harsh, high temperature environments, Dunlop Equipment's pressure-reducing valves are trusted by many of the world's major airframe and engine manufacturers.
Solenoid valves - Designed for a variety of applications including the control of engine bleed valves, Dunlop Equipment solenoid valves are cost-effective and offer very high levels of reliability in harsh environments including long term operation at elevated temperatures. Designed within strict guidelines, these valves are used on many engine platforms in service and have accumulated more than 300 million fleet hours.
Air/oil separators - In response to increasing regulation concerning the discharge of atmospheric pollutants, Dunlop Equipment's wide range of air/oil separators provides an effective means of removing oil particles from discharge air. Dunlop Equipment air/oil separators utilise Retimet®, a unique material developed by Dunlop Equipment featuring three-dimensional metal foam structures which exhibit excellent properties when used as the key element in centrifugal fluid/particle separators. Retimet® air/oil separators are now recognised by many major jet engine manufacturers as offering the most reliable and cost-effective solution towards reducing oil consumption. A full custom design service is available allowing performance and space envelope predictions to be accurately made before hardware manufacture.
Environmental control valves - Dunlop Equipment manufactures a range of environmental control valves to control temperature and pressure. This enables the safe and reliable use of engine or auxillary power unit bleed air to control the environment within the cabin, cockpit or stowage compartments. From simple non-return valves to highly efficient electro-mechanical regulators, Dunlop Equipment can meet the needs of the modern aircraft system.
Retimet® - Retimet® is a special metal foam material developed and manufactured by Dunlop Equipment. The material is versatile in shape and form and has extraordinary properties which render it suitable for very diverse applications in harsh environments. Retimet® is an inert material which is resistant to temperatures up to 900°C. This allows it to be used in a variety of other applications such as noise attenuation, flame arrestors and for flow straightening in ducting.
