The valve box is used to operate air-assisted VBG couplings (open/close PA, open AM). The box is specially designed for mounting in cabin. The construction is made to exclude handling errors, and it can be easily manoeuvred even with gloves. The coupling is operated with a manual valve that has been developed especially for VBG's high demands on safety and function. The box, which is made of a very strong and impact-resistant lightweight material, can be mounted in different directions and is easily connected with push-in nipples. Valve Box Kit contains a valve box, mounting bracket, 2 air hoses (Ø6 mm and Ø8 mm) and protective housing.
