structural characteristics

● Fully sealed design

The advanced fully sealed structure ensures that the valve can achieve zero leakage under any working conditions. From the valve body to the bonnet, from the sealing surface to the connection part, everything has been carefully designed and strictly sealed to effectively prevent the leakage of media and the entry of external impurities, and ensure the purity of the fluid and the stability of the system.

● Bellows protection

Built-in high-quality bellows can effectively prevent the ring from dressing and wearing on the valve stem, and at the same time prevent external impurities from entering the valve stem movement area to ensure long-term stable operation of the valve. The bellows and the valve stem cooperate closely to form a double sealing barrier, further improving sealing performance.

● Precision sealing component design

Adopt "bellows seal" and "graphite filler" seal, and the dual seal design ensures that the seal components can maintain excellent sealing performance under various media and working conditions.

● Valve position display design

The valve position display design is adopted to open and close the valve, and the process is visualized.
