HOME > SOLUTION > 2RD SEALING METHOD

2RD SOFT & METAL SEALING

2RD sealing method we named has increased seat durability of valve more than
12,000 times.

We cut the needless contact area of disc where the crown radius edge and small
radius edge.

This cause has strong durability and Low torque at high pressure or high temperature By change only the seat, maintenance fee is reduced.

Installation and dismantling are very simple

It is possible to change the valve on existed pipe line due to designed by ANSI Codes.

"New Innovation for Butterfly Valves - 2RD Valve Development of 2RD Sealing method (Soft, Metal Seat)"

1) Developed a valve generating no friction between disc and seat by adopting double eccentric structure there in for the first time (Previously field international patent applications regarding 2RD sealing process. PCT/KR02/00452)

2) Zero leakage achievement Our company has filed a patent application regarding a novel 2RD sealing method in metal sealing a butterfly valve in the name of three inventors including research professor with a technical assistance by INJE university Engineering Department in Korea. 2RD Sealing method is the best sealing method devised on excellent geometric analysis, which may solve the problem of difficulties in manufacturing. e.g. grinding machinery. arisen in triple eccentric structure due to the incompletion of geometric analysis.

The below 2RD sealing method enables the manufacturing of valves on a common shelf by adopting A seismic focus processing method as well as realizing frictionless sealing with only using a double Eccentric type valve, which makes it possible to produce the worlds high quality products in a large Scale while providing in a lower price compared with that of other company.
