Deals with delivery of high-pressure control valves, reduction-cooling stations, filtration stations, hermetic, high-speed and other special closing devices for demanding applications with high requirements for technical and nuclear safety. For a long time co-operates with world leaders on the valves market.
Nowadays it is a support division for procurement of more demanding components with an impact on nuclear and technical safety for other divisions. At the same time it started distribution of own products from manufacture division production. Currently it is able to provide the job of package supplier of mechanical components for big industrial project.
Bypass turbine station can be deservedly names as the most complicated combined valve which has to combine maximal operational reliability, it means ability of immediate start-up from cold condition, continuous variable control, velocity and safety of actuator´s opening, ability of repeated start-ups, high level of tightness in closed condition, ability of immediate reduction of steam pressure and temperature from critical parameters to low parameters for the condenser. We are talking about application where there is no compromise. ROEZ is the supplier of the most advanced bypass stations of DSCV type on global market with a number of successful installations and satisfied customers.
