Structural characteristics:

• When the valve is opened, the sealing surface has been relieved and the wear of the sealing surface is small.
• Double-sided hard seal and steam-assisted seal make the seal reliable.
• The two valve discs are relatively independent to compensate for manufacturing errors.
• Non-self-locking design, small opening moment;
• Methods Labial seal was used to avoid leakage of medium.
• The valve stem adopts the structure of double packing in series, and the sealing is reliable.
• The valve body has only one disassembly port and few leakage points.
• Set valve position feedback and body cavity pressure feedback.
