Structural advantages and characteristics

1. Meets the domestic and foreign advanced standard requirements, the seal is reliable, the performance is fine, handsome the appearance.
2. The damper plate and the valve seat packing surface are too vertical (satellite) with the iron-base alloy built-up welding or the department the cobalt base hard play built-up welding to become, wear-resisting, thermostable, ani-corrosive, the anti-abrasion performance is good, and the service life is long.
3. Using wedge-type flexible gate structure, medium and large caliber set bearings, switches flexible, open and close easily.
4. Stem quenched and the nitrogen treatment, with good corrosion resistance, scratch resistance, and wear resistance.
5. Can be used with a variety of standard pipe flanges and flange sealing surface types to meet various project needs and user requirements.
6. Valve body materials, variety, packing, and gasket can be based on actual working conditions or the user requests a reasonable option can be applied to all kinds of pressure, temperature, and medium conditions.
