Kent Centric (Concentric) Butterfly Valves
The most basic butterfly valve design is the centric or concentric type, where the stem passes through the disc centerline, positioned in the middle of the pipe bore. The seat is located on the inside periphery of the valve body. This zero-offset design, also called resilient-seated, relies on the flexibility of the seat rubber to achieve tight shutoff. During operation, the disc makes first contact with the seat at approximately 85° of its 90° rotation. These valves are typically used in low-pressure applications.

Centric Butterfly Valves with Fixed Liners
- Suitable for vacuum conditions, as there is no liner movement or wear.
- Handle high flow velocities and frequent operating cycles (e.g., open/close every few seconds).
- Commonly used above ground, with double-flanged types also applicable for below-ground installations.
- Applications: water, wastewater, gas, fire protection, and general industry.
Centric Butterfly Valves with Loose Liners
- A cost-effective solution for above-ground use where replacement and maintenance are convenient.
- Liners are easily replaceable without full valve replacement.
- Provides flexibility with a wide range of liner materials.
- Applications: water, wastewater, and industry.
