High Temperature Metal Seated Wafer Butterfly Valve ：
This is a high performance wafer type metal seated butterfly valve, designed for high temperature, high pressure and slightly corrosive industrial pipelines. The metal-to-metal sealing structure provides reliable zero leakage under severe working conditions, making it ideal for steam, gas, flue gas and high-temperature fluid applications. The valve is equipped with a worm gear handwheel operator for easy on-site manual control, with optional pneumatic or electric actuators for automated process control. The wafer design allows compact installation between two flanges, saving space and reducing installation cost. Available in a wide range of sizes and pressure ratings, it is commonly used in power plants, petrochemical plants, metallurgy and district heating systems. The robust construction ensures long service life even under frequent cycling and harsh operating conditions.
Product Features
1.High Temperature & Pressure Resistance: Metal seated design performs reliably in high-temperature steam and high-pressure gas pipelines. 2.Bidirectional Sealing: The double eccentric structure ensures tight bidirectional sealing and prevents backflow damage. 3.Low Torque Operation: Eccentric disc design reduces friction with the seat, minimizing operating torque and extending service life. 4.Compact Wafer Installation: Fits directly between flanges, saving installation space and project cost.
5.Multiple Actuator Options: Worm gear, pneumatic and electric actuators available for manual or automatic control. 6.Long Service Life: Withstands thousands of cycles under high-temperature and high-pressure conditions.
Application Industries This metal seated wafer butterfly valve is widely used in: Thermal power plant steam and flue gas pipelines Petrochemical refining and processing plants Metallurgical high-temperature gas pipelines Urban gas and district heating systems Industrial boiler and circulating fluid systems
