Main diamension:

 

 

Brief of butterfly:

 

Butterfly valve can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

 

Butterfly valve types:

 

Concentric butterfly valves - This type of valve has a resilient rubber seat with a metal disc.

 

Doubly-eccentric butterfly valves (high-performance butterfly valves or double-offset butterfly valves) - Different type of materials is used for seat and disc.

 

Triply-eccentric butterfly valves (triple-offset butterfly valves) - The seats are either laminated or solid metal seat design.

 

Triple-eccentric (offset) design

 

Triple eccentric (offset) Design prevents galling and scratches between the metal seat and the metal disc due to its unique design. The only time where the seal comes into contact with the seat is at the point of complete closure. Triple offset valves are generally used in applications which require bi-directional tight shut-off in oil and gas, LNG/NPG terminal and tanks, chemical factories, and shipbuilding. They are also used for dirty/heavy oil to prevent extrusion.

 

Wafer-style butterfly valves

 

The wafer style butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent any backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal; i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve.

 

Lug-style butterfly valve

 

Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.

 

A lug-style butterfly valve used in dead end service generally has a reduced pressure rating. For example a lug-style butterfly valve mounted between two flanges has a 150 psi pressure rating. The same valve mounted with one flange, in dead end service, has a 75 psi rating.

 

Use in industry

 

In the pharmaceutical, chemical and food industry a butterfly valve is used to interrupt product flow (solid, liquid, gas) within the process. The valves used in these industries are usually manufactured according cGMP guidelines (current good manufacturing practise).

 

 

 

Butterfly features:

 

1. Small and light , and easy installation and mintanance. It can be mounted wherever needed.

 

 

 

2. Siple and compact construction, quick 90 degree on-off operation.

 

 

 

3. Miniminzed operating torque, energy saving.

 

 

 

4. Flow curve tending to straight line. Excellent regulation performance.

 

 

 

5. Long service life Standing the test of tens of thousands opening/closing operations.

 

 

 

6. Bubbles-tight sealing with no leakage under the pressure test.

 

 

 

7. Wide selection of materials, applicable forvarious medium.
