The BVT-BO is an angle-style steam conditioning valve, used turbine bypass applications mainly in coal fired plants. 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. The BVT-BO is designed so that the steam flow is pushing the plug towards its open position. Water is passed through a hollow stem and injected through small holes in the plug. The water mixes with the steam inside the cage before being passed through the cage into the outlet. The valve plug design is optimized for low actuating forces, allowing for smaller and pneumatic actuators.
