Coaxial Valves in the Automotive Sector
Short switching cycles, high durability, compact design and
good compatibility with viscous media. Those were the
requirements of the Hungarian subsidiary of a German
automotive supplier for RSG’s coaxial valves.
The customer requested coaxial valves with a nominal size of DN40 and
DN50 to be used in an oil supply system which fills the automatic car
transmissions of a large German automobile manufacturer with oil. In this
case it is very important that the right quantity of oil is dosed to the trans­
missions at extremely precise time intervals. Several million switching cycles
can be realized with RSG’s coaxial valves. Therefore, they are operated
with significantly less wear and friction than commonly used valves.
In search of suitable products, the Hungarian company contacted RSG and
stated the necessary operating parameters. In addition to the general
requirements, the customer requested the coaxial valves to be equipped with
a flange instead of the commonly used threaded connection. The customer
further wanted a position request via inductive limit switches. Thanks to
RSG’s modular system, RSG was able to submit a quotation including the
requested specifications already on the following day based on the coaxial
valve of the 270 series.
Special development work was not necessary for conducting this order but
a mere combination of existing modular elements. “This method has the
advantage that we are able to quickly offer a customized and also proven
solution to our customers - and at very attractive prices”, explains Vitali
Gerlach, member of the technical sales team. “We certainly like developing
special solutions as well but our modular system Ventilutions which has
been further developed for many years allows for a quicker and less
expensive way to help our customers”, the industrial engineer points out.
The customer liked it and ordered the coaxial valves for its production
line already on the following day. The valves have been used there since
January 2018.
