Structural Features
Carbon Steel WCB Material: The valve body is made of carbon steel WCB, which has high strength and good high-temperature resistance, enabling it to withstand pressure and temperature changes under extreme working conditions.
Pressure Seal Design: The unique pressure seal structure ensures more reliable sealing performance as the system pressure increases, effectively preventing medium leakage.
Welded Structure: The valve body adopts a welding process, which enhances structural stability and integrity, and reduces the leakage risk that may be caused by bolted connections.
Y-Type Flow Channel Design: The streamlined Y-type flow channel design reduces fluid resistance, improves medium flow efficiency, and at the same time minimizes the erosion of the valve interior by the medium.
Butt-Welded Connection: The butt-welded (BW) connection provides a firm link with the pipeline system and excellent sealing performance, making it suitable for high-pressure and high-temperature working conditions.
Valve Stem Blow-Out Prevention Design: The valve stem is equipped with a blow-out prevention device, which ensures safety during high-pressure operation and prevents the valve stem from being blown out due to medium pressure.
Fire Safety Design: Compliant with relevant fire safety standards, the valve can maintain sealing performance even in case of fire, preventing medium leakage and ensuring system safety.
