structural characteristics

Fully lined with fluorine technology, the inner cavity of the valve body, gate plate, and valve stem surface are all covered with F4 fluoroplastic layer, which only comes into contact with the medium and has excellent corrosion resistance.

The wedge-shaped gate structure, combined with the elastic compensation of the fluoroplastic valve seat, ensures bidirectional sealing and achieves zero leakage of the medium.

Driven by a high torque hydraulic actuator, it has strong output torque, fast response speed, and can achieve emergency cut-off function.

Carbon steel cast valve body, with high outer strength and inner lining fluorine corrosion resistance, suitable for medium and low pressure strong corrosion working conditions.

The valve stem adopts an anti blowout structure, combined with fluoroplastic seals, effectively preventing medium leakage and improving operational safety.

Design specifications: comply with GB/T 12232 and HG/T 3704 standards.

Drive mode: hydraulic (expandable to pneumatic, electric, manual).
