A resilient seated butterfly valve is a widely used industrial valve designed for reliable sealing and efficient flow control in low- and medium-pressure pipeline systems. The valve uses an elastic sealing seat, usually made from rubber materials such as EPDM or NBR, to create tight shutoff performance.
The resilient seated butterfly valve is commonly used in water treatment systems, HVAC applications, fire protection systems, and industrial utility pipelines because of its excellent sealing capability, lightweight design, and cost-effective operation.
🔍 What Is a Resilient Seated Butterfly Valve?
Structure and Design
A resilient seated butterfly valve typically includes:
- Valve body
- Rotating disc
- Elastic sealing seat
- Stem shaft
- Manual or automated actuator
The resilient seat creates a secure seal between the disc and valve body.
Working Principle
The valve operates through disc rotation:
- Open position allows fluid flow
- Closed position compresses the resilient seat to stop leakage
This design ensures efficient and reliable shutoff performance.
