Abstract

The forming technology for reducing valve was analyzed

and the HPb59-1brass reducing valve was produced by hot extrusion process.In addition

the finite element model of the hot extrusion forming for the reducing valve was established to simulate liquid metal flow during the forming process of the reducing valve.Based on the simulated results

hot extrusion technology was presented and the die was designed.The practical application shows that the reducing valve can be produced by hot extrusion process.
