Dn15~300 1.6~16 Mpa High Quality Wedge Gate Valve

DN15~300 1.6~16 Mpa high quality wedge gate valve

Pressure of Nominal PN: 1.6~16 Mpa
Diameter of Nominal DN: 15~300 mm
Design and Manufacturing GB/T12234


Structure and Features:
1. Good selection of materials which meet both domestic and international standard. All materials have high qualities.
2. It meets the needs of both domestic and international advanced standard, and it has robust sealing, excellent performance and artistic design

3. It has advanced and applicable sealing. Sealing surfaces of the gate and the valve seat are welded with Stellites of different hardness Cobalt-cemented carbide. It has robust sealing, high hardness, wear-resistance, high temperature bearing, corrosion-resistance, good abrasion-resistance and long service life.

4. With nitrogen-treated surface as well as the quenching and tempering treatment, the stem has good corrosion-resistance, abrasion-resistance and wear-resistance.

5. Adopting a flexible wedge gate structure, which means there are an angle between the sealing surface and the vertical center line. That is, these two sealing surfaces form a wedge, which cuts off piping medium. Large and medium caliber set of thrust bearing which decrease the friction and can be opened/closed easily.

6. A variety of piping standard flanges and flange surface sealing methods are available, which can satisfy a variety of project needs and user requirements.
