Product Details

【Product Introduction】:

Class 150 Triple Offset Butterfly Valve is one of main products of ZFVALVES.Mainly the features as followings:

1) Triple offset provides a tapered sealing surface that minimizes wear between the seat and the seal,

2) the superior seat surface is minimized to reduce the operating torque of the valve;

3) Design and manufacture API609,End flanges dimension ASME B16.5.

API609 has in fact become an international specification for valves used in industrially important pipelines. Class 150 Triple Offset Butterfly Valve is designed and manufactured in strict accordance with API609 specifications, which guarantees that valves are used in all industrial fields.

Product Features】:

1) Double safety structure:

In order to prevent deformation of the disc caused by fluid pressure and temperature, misalignment of the valve stem and engagement of the sealing surface, two independent thrust rings are respectively arranged on the lower side of the disc, thereby ensuring the valve in any working condition. Normal work under

2) Body seat structure:

There are two types of seat mounting structures for the three eccentric butterfly valves, most of which are mounted on the disc for convenience, but our Class 150 Triple Offset Butterfly Valve uses a body seat construction to mount the seat on the body. 

3) Thin layer valve seat structure:

The valve seat of the Butterfly Valve is made of a laminate of stainless steel sheets and graphite sheets. This structure can effectively prevent the influence of tiny solids in the medium and the sealing surface engagement caused by thermal expansion. Even if there is a slight damage, there will be no leakage.
