BVT-TB
BVT-TB turbine bypass valve
The BVT-TB is an angle-style steam conditioning valve,
used for both process and turbine bypass applications. It is
designed to reduce temperature and pressure of steam to
match downstream requirements. Pressure is controlled using
a proven trim technology which reveals a series of perforations
in the valve cage as the plug moves. Steam is then passed
to the outlet through a series of pressure reduction stages,
selected specifically for the operating conditions on a caseby-
case basis in order to reduce noise. Valve Plug design is
optimized for low actuating forces, allowing for smaller and
pneumatic actuators. Control of temperature takes place in the
outlet, where a number of spring-loaded spray water atomizing
nozzles are installed perpendicular to the steam flow. The
selection, placement and design of these are chosen to match
the desuperheating requirements of the system as well as
reducing risk of free water being injected into the downstream
piping.
