Metal sealed plug valve

Hard sealed plug valves are becoming more and more popular in the international market because of their robust design and excellent sealing performance. By using advanced materials and eliminating traditional threaded connections, these valves have higher strength and better sealing capability. In addition, their reduced weight makes installation more convenient, reducing construction costs and saving time.

Design Advantages

The hard seal design effectively prevents internal and external leaks.

Eliminating traditional bolts reduces valve weight and simplifies installation.

Minimum flow resistance when fully opened ensures efficient operation.

Quick on and off functions increase operational efficiency.

Rugged construction ensures durability in demanding applications.

Fewer components reduce maintenance costs.

Equipped with fire and anti-static devices to ensure safe operation.
