What are the possible applications for Schubert & Salzer valves in the automotive, aerospace and shipbuilding industries? The answer: an infinite number.
In vehicle manufacturing, the range of applications stretches from engine test stands to test stands for fuel cells, from heat exchangers for sports cars right through to the use on the vehicle itself – such as for controlling the water feed in fire engines. In paint shops, our valves assist in dosing paint and in engine block casting shops, our high precision sliding gate valves regulate compressed air. Their high rangeability ensures the parameters remain constant during the casting process. The paint area also requires precise humidification and temperature control to ensure high quality; again the sliding gates valves provide the precision needed to regulate these various zones. The cleaning and deburring of work pieces for the automobile industry is another area of application. Here, the cleaning medium is sprayed at high pressure onto the surface being cleaned.
Dealing with pressure is found also in aircraft production, where Schubert & Salzer valves are used in the testing of aircraft engines and in cabin pressure simulations. The air pressure in the cabin is maintained at specific pressures during flight, which corresponds to the pressure at an altitude of just over 1 mile. However, the actual outside air pressure when the aircraft is flying at 36,000 feet is substantially lower, as a result of which the aircraft fuselage expands somewhat. This effect, which can cause material stress over time, is simulated by means of a pneumatic unit. The compressed air for this is controlled by valves from Schubert & Salzer.
Extremely high safety standards apply in shipbuilding also. In this case, because of severe space restrictions in particular, the valve used must be of compact construction, have low weight and, despite wide rangeability, must be easy to maintain. For this reason, our sliding gate valves in particular are highly popular and are used, for example, in the control of thermal oil (for heating circuits), for water processing, for the control of fresh, cold and hot water, and in the generation of steam.
On main and auxiliary engines of big container and cruise ships segmented disc orifices from Schubert & Salzer are used to adjust the cooling water circuit on the individual cylinders. These manually adjustable throttling elements can regulate precisely the cylinder temperature of 2 or 4- stroke marine diesel engines during commissioning or later at any time on sea.
