BVT-SCG pressure reduction valve

The BVT-SCG is a globe-style 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 static pressure stage may also be present in the outlet, to reduce the pressure drop over the cage and thus the noise caused by the trim.

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.
