Q41H metal hard seal ball valve is a high-performance ball valve product developed by our company.The valve seat adopts a metal sealing structure loaded with leaf springs,which can be easily opened and closed at high temperatures.The sphere and valve seat are treated with special hardening,and the sealing surface is not scratched.The manual hard seal ball valve has bidirectional sealing function.Main application:Metal hard seal ball valves are used on various pipelines with working temperatures of-29~425℃(carbon steel)or-40~550℃(stainless steel)to cut off or connect media in pipelines.Different materials are selected,and metal hard seal ball valves can be applied to various media such as water,steam,oil,nitric acid,acetic acid,oxidizing media,urea,etc.
Characteristics of Metal Hard Sealed Ball Valve Products
1.Advanced valve seat:The valve seat is designed based on years of experience in ball valve manufacturing,ensuring valve sealing,low friction coefficient,small operating torque,multiple valve seat materials,and wide adaptability.
2.Accurate switch handle:Using a flat head valve stem,the connection with the handle will not be misaligned,ensuring that the switch status indicated by the handle is consistent with the valve.
3.Locking device:To prevent misoperation of valve opening and closing,there are locking holes in the fully open and fully closed positions of the valve to ensure that it is in the correct position.
4.Valve stem anti flying structure:The valve stem is bottom mounted to prevent it from flying out under pressure,and can also form metal contact with the valve body after a fire,ensuring the valve stem is sealed.
