Valve and fire damper for exhaust air.

Is used to prevent spreading of fire and smoke into duct systems. A spring loaded melting fuse shuts the valve when the temperature exceeds +70 °C.

Bayonet holders connect to socket VRGU, VRGL or VRGM.

Socket VRGL is as standard delivered together with KSUB. This case is shown in the ordering example below.

If socket VRGU or VRGM is wanted instead this socket has to be specified in the type field.
