韩国KOREADAE-RYUN ENGINEERING.CO.,

 

With over 20 year rich experience and technology, our company

manufactures butterfly valves, v-notch ball valves, and etc.

 

As we look back over the past years, we realize that we have a lot to be

thankful for the opportunity to serve you.

 

We also appreciate your support and feedback. We do our best to develop

new technology to be the world's best company.

 

Our products are used in South Korea's leading steel makers, heavy

industries, and Chemical Industry.

 

Some are also used in Korean government department such as Korea

Water Resources Corporation and Rural Community Corporation.

 

The butterfly valve, one of our well-developed products, is a high-

performance butterfly valve (NELDISC TRIPLE OFFSET SEATING PRINCIPLE)

 

It is very suitable for high-pressure situation and also is a low torque valve.

 

It has two kinds of seat, soft and metal.

 

The v-notch ball valve (LEAKAGE CLASS VI) is Teflon. The metal valve can

be for LEAKAGE CLASS VI.

 

We provide the high quality products at low fair prices so that we have the

competitive advactage.

 

Our company has been certified to be in conformance with ISO 9001,

ISO 14001

The series 10 butterfly valves has been developed for a large number of 

  applications throughout process industries. 

The series 10 high performance butterfly valves are mainly used for the

  control of fluids flowing in large valve at low differential pressure.

It offers added advantages such as simple structure and cost. 

 

*Part List / The Triple-offset

 

 

- The Triple-Offset Butterfly Valve Provides a bi-directional

bubbletight shut-off.

- This geometry ensures that the disc seal contacts the body seat

only at the final shut-off position.

- Without rubbing or galling, providing a troque generated resilient

seal with sufficient "wedging" to ensure a uniform seal contact.

 

Characteristic

1. the shift effect into sheet side and rotation when the valve is

openning and closing.

2. The generation of compressing effect between Disc and Sheet.

3. The contact is generated as soon as valve is completely closed.

4. Decreased wear-land by first contact between sheet and valve.

5. Extention of Life time for valve sheet and disc.

6. Prevent warping of sheet and disc

7. Less torque generation at high voltage

8. Reduced noise when valive is open
