Soft seat : Leakage Class VI

Metal seat : Leakage Class VI


	프로세스 산업을통해서 많은 부분에 적용하기위해 버터플라이 밸브가 제작되었다.
	버터플라이밸브는 작은 압력차이를 가진 큰유량의 유체를 조절하기
	위해 주로 사용되다.
	그래서 버터플라이밸브는 간단한구조로 자가에 설치하는 이득을준다.

	기존의 컨트롤 밸브에비하여 적은중량으로 큰 Cv 를 처리할수있다.
	60도를 통해서 컨트롤 할수있도 90도를 통해서 on-off로 사용할수있다
	ramge-agility 가 높게 컨트롤할수있다.

	배관 size :3"-24"(80mm-600mm)
	밸브 rating:ANSI 150 to 300 ,JIS10K to 20K PN6-PN20
	최대 자동온도 :450도 까지
	면간 :ISO 5752-1982에 적용된 면간

액화가스 저장소의 유체조절,스팀보일러,폐수처리설비,제지업 체철소등사용

	스프링타입 공압다이아프램 액츄에이터를 비롯하여 다양한 타입의
	작동방법 설치가능
	공압 피스톤 type의 에츄에이터도가능 합니다.
	게다가 전동식,전동유압식,유압식 에츄에이터도 사용가능합니다

- 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
