Park & Shunt Valve

The basic park and shunt valve is used to actuate and release the service brake, and also the spring brakes on unhitched trailers. It does not provide a pressure protection feature like TEM, TrCM or TrCM+

352 044/045 xxx variants don't contain an Emergency function, therefore an additional Relay Emergency Valve (REV) with Emergency function is required.

352 046 xxx variant includes an emergency function by using the spring brakes. In addition to this valve there is no additional REV required.
