Power station check valve: product structure characteristics

1. Product design and manufacture shall be used in accordance with ANSI B16.34 and E101, which can be used with imported equipment

2. Pressure self-sealing structure is adopted in the valve middle cavity
Higher the internal cavity pressure, the better the sealing performance
Two ends of the branch pipe are welded to each other at both ends to meet different takeover requirements

3. Valve durable components are made of high-quality heat-resistant alloy steel, high-temperature performance, high-pressure, durability, safety and reliability

4. Sealing surface of disc and seat is made of stellite cemented carbide surfacing, which is wear-resistant and high-temperature resistant, with good abrasion resistance and long service life

6. Disc is rotated around the pin shaft outside the seat to reduce the impact when it is closed

7. Built-in pin shaft structure to reduce leakage and use more reliable
