Resilient Seated Butterfly Valve

The operating temperature range is -20°C to 120°C due to temperature limitations of the sealing material. Resilient seat butterfly valves are an excellent choice for continuous adjustment and control, with pressure ratings up to 250 psi and vacuum to 24" Hg.

Resilient seated butterfly valves, also known as centerline elastic seat soft sealing butterfly valves, feature a design where the center of the stem, disc, and body align on the same axis. This simple structure facilitates easy manufacturing. However, the disc and valve seat are constantly in a state of compression and abrasion, resulting in higher resistance and faster wear.

To mitigate compression and abrasion while ensuring sealing performance, the valve seat typically utilizes elastic materials such as rubber or polytetrafluoroethylene (PTFE).

Choosing the right seat material is critical for valve performance and longevity.

• Water and Wastewater Treatment: For controlling the flow of clean water, sewage, and treated effluent.
• HVAC Systems: In heating, ventilation, and air conditioning systems for regulating water flow in heating and cooling circuits.
• Chemical and Industrial Processes: Suitable for handling a variety of mild chemicals, slurries, and other industrial fluids compatible with the seat material.
• Irrigation and Fire Protection: Used in sprinkler systems and fire protection lines due to their reliable shut-off capability.

Shield resilient seated butterfly valves feature a one-piece or two-piece stem design with high strength without pins, using an inner valve stem connected to the valve. Available in wafer, lug, and flange connection types.
