◆With a lightweight structure, valve body and disc are machined of steel plate, with lightweight and
compact, easy installation and maintenance. It fits for the application of large diameter.
◆Disc is a center-lined design, small open torque, without attrition and jumping phenomena. External
circle of disc and internal wall of valve body coordinate well when shut off, without jam fault, easy
◆An appropriate expansion clearance between optimal-designed elliptic disc and valve body can
effectively prevent the seizing-up resulted from thermal expansion and contracting under elevated
◆Nominal Pressure: PN2.5，PN6
◆Leakage Rate: less than 2% of rated CV
◆End Connections: wafer, welded, flanged
