① Valve disc

② Valve casing

③ Cross bar

④ Threaded spindle with lock nut


Extract air valves extract air from rooms and lead it into the extract air part of the air conditioning system.

Type LVS disc valves have a valve disc that can be turned. This simplifies the volume flow rate balancing adjustment during commissioning.
