1. Spherical Disc Design:

   • The valve features a spherical-shaped disc or element that rotates to control flow. The spherical design allows for a more effective seal and flow control compared to traditional butterfly valves.

2. Butterfly Valve Mechanism:

   • Like a conventional butterfly valve, it has a disc or plate that rotates to open or close the flow passage. The key difference is the shape of the disc, which is spherical.

3. Compact and Lightweight:

   • The spherical disc design often allows for a more compact and lightweight valve compared to other types.

4. Sealing:

   • The spherical shape of the disc can provide better sealing characteristics, which helps prevent leaks and improve performance.

Uses:

1. Flow Control:

   • Used to control the flow of various fluids, including gases, liquids, and slurries. The spherical disc helps achieve smooth and precise control.

2. Isolation and Regulation:

   • Suitable for applications where isolation and regulation of flow are required. It can be fully closed to block the flow completely or adjusted to regulate the flow rate.

3. Pipeline Systems:

   • Commonly used in pipelines where space is limited and a compact valve is needed. The spherical disc design can be beneficial for high-pressure and high-temperature applications.

4. Industrial Applications:

   • Found in industries such as water treatment, chemical processing, oil and gas, and HVAC systems. It is useful in processes where reliable and effective flow control is critical.

5. Improved Performance:

   • The spherical shape can reduce turbulence and pressure drop compared to traditional flat-disc butterfly valves, improving overall system efficiency.

Advantages:

• Enhanced Sealing: The spherical shape provides a more effective seal compared to flat discs, reducing the risk of leakage.
• Reduced Pressure Drop: The design can minimize pressure loss across the valve, improving energy efficiency.

"FOCET" MAKE Lug-style butterfly valves are usually composed of metal such as ductile iron or steel. They feature threaded tapped lugs positioned on the valve flanges for bolt connections.

Lug-style butterfly valves are suitable for end-of-line service but a blind flange is always recommended. Lug-style butterfly valves are manufactured to be compatible with either pneumatic or electric actuation. Disc and seat material should be determined based on application and flow media.

CONFORMITY TO CODES AND STANDARDS SPECIFICATIONS

 

"FOCET" MAKE Butterfly valves usually consist of a compact housing, the disc for shutting off or releasing the flow, a shaft (with bearings and seals) and the actuating element. The actuating element is used to open or close the valve disc by a 90° rotary movement. When the valve is fully open, the disc is parallel to the direction of flow, in the medium flow.

Butterfly valves are usually used purely as shut-off valves for on/off operation. Since the valve disc is in the flow path even when fully open, it is not recommended for use with media containing solids. A full, free passage is therefore not given here. This means that cleaning of the pipeline, e.g. by pigs, is not possible.

Butterfly valves are also suitable to a certain extent for throttling or regulating the flow medium, although they have the following disadvantage due to their design. The further the valve disc is closed, the more the flow velocity increases in the passage. This causes cavitation and water turbulence, which can damage the internal components, especially the seals.

The installation position of the butterfly valve is variable as long as the valve shaft is horizontal.
