Performance Design Characteristics of Triple Eccentric Butterfly Valve
发布时间：2018-12-21 来源：艾德威尔•瑞拓
Triple Eccentric Butterfly Valve has the advantage of soft seal butterfly valve, but it still belongs to hard structure in structure. Let's have a look at the performance design characteristics of Triple Eccentric Butterfly Valve.
Triple Eccentric Butterfly Valve is a hard sealing structure. It breaks through the temperature and pressure limitations of soft sealing butterfly valve, and adds a unique eccentric disc oblique cone. It not only utilizes the original cam effect, completely eliminates the friction between the valve plate and the seat, eliminates the possibility of wear and leakage, but also has the characteristics of tighter closure, looser opening and longer service life.
Design features:
This industrial valve has the advantages of small size, light weight, large flow rate and space saving. Reliability and cost advantages brought by special structure. Soft seal seat and hard seal seat are two structural types. Friction-free closure allows easy operation with minimum torque. Soft seat zero leakage, hard seat VI leakage.
Performance characteristics:
Special modular three-eccentric design structure is adopted, with small opening and closing torque.
When the valve plate is opened at 1.5 degrees, it is separated from the seat. When the valve is opened and closed, there is almost no wear and tear between the valve plate and the seat, which improves the service life.
All adopt modular design and production with strong interchangeability. Valve plate and seat of any structural type can be exchanged and matched to achieve close break.
Nominal path: 3B-24B (DN80-DN600)
Nominal pressure: ANSI 150, 300 JIS 5K, 10K, 20K PN0.6, PN1.0, PN1.6, PN4.0
Valve body material: WCB, CF8, CF8M
Valve Plate Form: Partial Spherical Shape of Tri-eccentric Structure
Connection mode: clamp type and flange type
Flow characteristics: approximate equal percentage
Temperature: - 196 ~+500 ~C
Permissible Seat Leakage: Hard Sealed ANSI CLASS IV, V, VI Soft Sealed ANSI CLASS VI or Zero Leakage
Each butterfly valve has its more suitable application scope and conditions because of its different design characteristics and mechanism. Understanding its design characteristics will help us to better play its use value. More knowledge about Triple Eccentric Butterfly Valve is available in Ruitou, Beijing.

Metal seal seats with leakage can reach CLASS VI, or even zero leakage.
