HAM-LET Needle Valves with Rupture discs were designed to be mounted on HAM-LET sample cylinders, the Ruptur e disc provides protection against over pressure in sampling units by venting the media to the atmosphere.

A Ruptur e Disc unit can be easily replaced in the field while the valve r emains connected to the sampling unit.
