Product Description

Features

1. Reasonable product structure, reliable sealing, excellent performance and beautiful appearance

2. The product can be selected for soft or hard sealing according to different working conditions. Welding on the sealing surface, the Co-based hard alloy has better wear resistance, corrosion resistance and abrasion resistance. Long service life.

3. Low pressure opening valve can be fully opened at low pressure difference,

4. Internal pin design reduces leakage and reliable use.

5. Self-sealing sealing design is used in the middle of the cavity. Sealing capacity can be improved with increasing pressure to provide sealing performance.

6. the material of the part and the size of the flange and butt welding can be reasonably selected according to the actual working conditions or user requirements to meet different engineering needs.
