Description

Tasks
Reheater safety valves prevent excess pressure in the reheater. When the valve opens, the hot reheater steam is blown off via the connected rising pipe and attached silencer through the roof into the atmosphere. The valves thus interrupt the otherwise closed water-steam cycle. Unlike the HP/IP/LP bypass valves, there is no steam cooling.

Versions
Forged valves in angled form

Advantages
Simple, reliable design
Safety function with cup spring assembly in the positioning cylinder
Disc spring assembly and steam pressure act in an upwards direction to open the valve safely
