Technical Specifications
Product Overview
Industrial Turbine Inlet Butterfly Valve
This high-performance turbine inlet butterfly valve is engineered to protect and ensure the safe operation of turbine units by isolating the upstream water source. It serves as a critical safety mechanism during maintenance or emergency scenarios, such as runaway speed conditions, by effectively cutting off flow from the spiral case. The valve utilizes a double-eccentric disc design to ensure structural integrity and high flow efficiency, combined with advanced hydraulic and electric control systems for maximum reliability.
