BVT-TB steam conditioning 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 case-by-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.
