The brass safety valve suitable for water supply and drainage system and low pressure piping line.the all of the parts are the brass material.

Safety valves with threaded connections are used for handling small and medium mass flows. The LESER threaded connection safety valves are notable for their wide range of set pressures, compact overall dimensions and light weight.
