BVT-SC pressure reducing valve

The BVT-SC is a pressure reducing valve used in steam turbine systems, typically used in vent to atmosphere applications. In this application, the valve is placed in a steam pipe branched from the connection between boiler and turbine allowing the steam to be vented to atmosphere in case of a turbine trip. Pressure regulation is taken place in the valve trim where a plug reveals a series of perforations in the valve cage. A set of static pressure reduction pipes may also be installed in the outlet, depending on the pressure drop, providing noise reduction. The BVT-SC can also be combined with a downstream desuperheater such as the BVT-DLP to perform steam conditioning in installations where downstream straight pipe lengths do not allow for desuperheating in the pressure reducing valve.
