Triple Offset Butterfly Valves: The Pinnacle of Zero-Leakage Technology
Standard butterfly valves often struggle in high-heat or high-pressure environments due to constant friction between the seat and the disc. The FlowBiz Triple Offset design eliminates this friction entirely through a unique geometric configuration, allowing for a metal-to-metal bubble-tight seal.
Understanding the Three Offsets
The "Triple Offset" refers to three distinct geometric shifts that ensure the disc only touches the seat at the final point of closure.
- First Offset: The shaft is located behind the sealing surface. This allows the disc to have a continuous sealing path around the entire circumference.
- Second Offset: The shaft is offset from the vertical centerline of the valve. This creates a "camming" action, lifting the disc away from the seat immediately upon opening, which eliminates friction during 80% of the stroke.
- Third Offset: The sealing components are machined into an asymmetrical conical shape. This ensures that the disc and seat only make contact at the final $90^{\circ}$ angle of closure.
Key Benefits of the FlowBiz TOV Design:
- Friction-Free Stroking: Minimizes wear on sealing surfaces, resulting in a significantly longer service life.
- Zero Leakage: Achieve a bubble-tight seal even in extreme temperatures where soft seats would fail.
- Torque-Seated: The sealing is achieved through the torque of the actuator rather than the elasticity of a seat, ensuring a more reliable shut-off.
- Anti-Blowout Stem: Designed for maximum safety in high-pressure applications.
Classification by Connection Type
FlowBiz offers the Triple Eccentric design in various body styles to fit any piping requirement:
Connection Type | Best Used For |
Flanged End | Heavy-duty pipelines requiring robust, double-bolted security. |
Wafer Type | Compact, space-saving installations between two flanges. |
Lug Type | End-of-line service and downstream maintenance flexibility. |
Butt-Welded | High-pressure, high-temperature systems where zero external leakage is critical (e.g., steam). |
