structural characteristics

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

Angular flow channel design ensures smooth medium flow and reduces particle retention, making it suitable for strongly corrosive media containing particles.

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 high 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 4213 and HG/T 3704 standards.

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