900# High Pressure Butterfly Valve

Product Description


Standard Specifications:

Body Size:3”~64”(DN80~DN1600)
Rating:ANSI 900#,1500#;


Body Material:WCB,WC6,CF8,CF8M,CF3M etc

Disc:Triple eccentric type segmental ball disc
Body connection:Wafer type ,RF,Lug type
:-45~+500℃(Special for 800℃)



1.Triple eccentric designing construction has special throtting and shut-off performance.

2.Three-link structure,triple eccentric reflected on the disc;

3.Simple Processing ,Easy assembly and disassembly

4.The angle of Seat is only 1.5°with no-friction, small torque of start and close .

5.The life of seat is long with steady performace;

6.Modulering product,assembly makes all parts of the valves exchanged well ,costs the customer lower for the spare part.


Performance Features:

1.Triple eccentric design,realiable and long life

2.No-friction, low torque ,Tight shut off

3.Modular design ,exchangable seal ring cost lower for maintance 

4.laminate seal ring

5.Steam jacket type can be manufactured


Disadvantage and Problem:

Double-eccentric butterfly valve

1.Through the axis of rotation to drive the disc rotate to make the valve plate outside of the sphere gradually extrusion to seat and play a part in sealing. The disc and seat make a big friction and increase the axis of torque.Because the disc and seat regular rub,it influnce the body’s life.

2. The eccentric angle on the Seat that processing and assembling is diffcult.After testing and boring,the body and the axle hole of disc is diffculty to clamp, the machining accuracy can’t be guaranteed. It is difficult to achieve the seat leakage sealing requirements.

3. Every body corresponding to a disc and seat, the disposable use are not interchangeable.



Solve the problem’s points and purpose:

1..Double eccentric butterfly has large friction between the disc and the Seat.The direction of the friction between the centerline of the body produces a Angle,so add sealing face between the disc and the centerline of the body to greatly reduce the friction between the disc and the seat (sealing angle only 1.5°), opening and closing torque to reduce and prolong the life.

2.Put the three eccentric on the disc to make the body and disc, seat and all components modular to assemble. Each parts all can interchangeability, manufacture process simple, warehouse management convenient.
