Fully Welded Ball Valve

The fully welded ball valve has become popular in the international market in recent years, because of the unique all-welded structural characteristics, the traditional threaded connection is canceled, the overall strength of the valve is improved, but also the sealing of such ball valve has been greatly improved, in addition, the weight of the valve is also greatly reduced, so that the installation of the fully welded ball valve becomes more convenient. The construction cost is reduced and time is saved.

Design Advantages

Fully welded structure effectively prevents the risk of internal and external leaks

Eliminating traditional bolts reduces the weight of the valve and facilitates installation.

When fully open, the medium can pass completely and the flow resistance is 0

Can be opened and closed quickly

Can be buried directly underground

Few parts and low maintenance costs

Fireproof and anti-static device
