The Electric Rubber Lined Butterfly Valve is a compact flow control valve designed for handling corrosive, abrasive, or viscous media. It integrates an electric actuator with a rubber-lined body, offering efficient automation and robust sealing.
Working Principle
A rotating disc, controlled by an electric actuator, regulates flow. Rotating the disc 90 degrees opens the valve (aligning with the pipeline for minimal resistance) or closes it (pressing the disc against a rubber seat to block flow). The electric motor enables remote, precise operation via signals like 4-20mA.
Key Features
- Rubber Lining: The body and seat are lined with durable rubber (e.g., EPDM, NBR), resisting corrosion from chemicals, wastewater, or slurries.
- Electric Actuator: Supports automated on-off or modulating control, with options like position feedback and manual override for reliability.
- Space-Efficient Design: Lightweight and compact, fitting easily into tight pipelines.
Applications
Common in water/wastewater treatment, chemical processing, and HVAC systems. Ideal for corrosive fluids, sewage, or industrial liquids requiring tight sealing.
Advantages
- Tight rubber-sealed shut-off to prevent leaks.
- Corrosion resistance extends service life.
- Low flow resistance saves energy.
- Easy integration with automated control systems.
This valve balances durability and efficiency, serving as a cost-effective solution for diverse fluid control needs.
