BVT-PB process bypass valve
The BVT-PB is a steam conditioning valve optimized for auxiliary and process steam. The application for process steam may range from petrochemical plants to pulp and paper, where the valve is typically installed in parallel to a steam turbine and controls the downstream pressure and temperature. Pressure reduction takes place in the valve trim as well as the outlet, where several pressure-reducing pipes are installed.
