D63H, D363H, D663H, and D963H PN10~PN100 three eccentric welded hard seal electric butterfly valves use precision J-shaped elastic sealing rings and three eccentric multi-level metal hard sealing structures. They are widely used in industrial pipelines with medium temperatures ≤ 400 ℃, such as metallurgy, power, petrochemical, water supply and drainage, and municipal construction, for regulating flow and carrying fluid.

Valve model
Common models include: d963h-6, d963h-10, d963h-16, d963h-25, d963h-40, d963h-64, d963h-100, d963y-6, d963y-10, d963y-16, d963y-25, d963y-40, d963y-64, d963y-100, etc.
Product Features
1. The unique design of three-way eccentricity ensures frictionless transmission between sealing surfaces, extending the service life of the valve.
2. Elastic sealing is generated by torque.
3. The clever wedge design enables the valve to have an automatic sealing function that tightens as it closes, with compensatory and zero leakage between sealing surfaces.
4. Small size, light weight, lightweight operation, easy installation, and reliable connection.
5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
6. The replacement part material can be suitable for various media and can be used for lining anti-corrosion (lining F46, GXPP, PO, etc.).
