Valves are used for various Applications on Trains

Extreme weather and environmental conditions, dust, vibrations, stress. The railway industry is a challenge that requires reliability and durability. Functioning valves installed to perform numerous tasks in various different areas of the train and railway transport sector are important to guarantee smooth processes in their relevant area of application.

Valves can be used to control the filling of wagons with bulk goods, for dosing and shutting off the transport of various different operating materials (e.g. water, sand, etc.) or to support the unloading process.

Thanks to the high-level technology and quality manufacturing, Pinch Valves from AKO UK meet the requirements of such a difficult sector.

Traction Control to Vacuum Toilets Controlled via Valves

Black water (wastewater from bathrooms and toilets that contains faecal matter and urine) from train toilets is removed using a vacuum system nowadays. Pinch valves from AKO UK control this process and are responsible for stopping and starting the suction.

Another application for pinch valves in the area of rail vehicles is the filling of sand vessels. The sand is used to optimise the braking of the train and to increase traction e.g. on wet rails. The sand from the boxes – loaded beforehand using a filling process controlled via a pinch valve – is spread in front of the wheels on the engine with aid of compressed air or a drop chute. It increases the friction between the wheel and the rail and thus shortens the breaking distance and improves traction.
