Selection of parallel single gate valve structure.
The cobalt-based cemented carbide is surfacing welded on the sealing surface of the valve seat. The floating metal hard seal + steam-assisted seal structure is adopted for the sealing pair to meet the purpose of zero leakage of the medium.
The design of coke shielding cover inside the valve body can effectively prevent coke powder from entering the valve cavity and prolong the service life of the valve.
