High performance safety valves made of brass, atmospheric discharge, with threaded connection

All aspects and special safety features of the "FKS" valves made of stainless steel have been fully implemented in this series. However all technical and safety features are contained in a brass body. These valves are an optimal solution with respect to their price / performance ratio for use on bulk transport vehicles and stationary silos.
