125S – Security DN50 Sampling Valve

The mechanical locking device secures the sampling procedure.
1. The sampling bottle (container) can only be removed if the piston is completely closed and if the purging valve is opened.
2. The piston can only be opened if the sampling bottle (container) is coupled on the outlet and if the purging valve is closed.

The sample is taken in the same way as the standard Famat sample valve. The indicator (A) shows the position of the piston. This indicator has to show ” closed ” to allow the security lock (B) to be moved to the open position. Only Then, the sampling bottle can be removed from its bayonet coupling. The piston is locked inside the valve until the sample bottle is refitted and the security lock (B) is moved to “closed”
