Electric Lining Butterfly Valve: Product Introduction
Overview
The Electric Lining Butterfly Valve is a highly specialized flow control device designed for applications requiring corrosion resistance, precise operation, and automation compatibility. Combining the durability of lined materials with the precision of electric actuation, this valve is ideal for handling aggressive media such as acids, alkalis, and corrosive chemicals. Its innovative design ensures reliable performance in industries like chemical processing, water treatment, and pharmaceuticals, where hygiene and resistance to harsh environments are critical.
Structural Features
1. Valve Body:
- Constructed from carbon steel or ductile iron, providing a strong and durable framework.
- The interior is lined with PTFE (Polytetrafluoroethylene), PP (Polypropylene), or PFA (Perfluoroalkoxy), offering exceptional resistance to corrosive chemicals and high temperatures.
- The lining ensures a smooth, non-stick surface, preventing material buildup and facilitating easy cleaning.
2. Disc:
- The disc is made of stainless steel or ductile iron, often coated with the same lining material as the body for consistent corrosion resistance.
- Designed with a low-profile, aerodynamic shape to minimize pressure drop and improve flow efficiency.
- Precision-machined for smooth operation and tight sealing.
3. Seat:
- The seat is made of PTFE or other chemically resistant elastomers, ensuring a bubble-tight seal even under low-pressure conditions.
- The resilient seat design reduces friction and wear, extending the valve's service life.
4. Stem:
- The stem is crafted from stainless steel for high strength and corrosion resistance.
- Designed with a self-lubricating bushing to reduce friction and ensure smooth rotation.
5. Electric Actuator:
- The actuator is made of aluminum alloy or stainless steel, offering lightweight yet durable construction.
- Equipped with position feedback, limit switches, and solenoid valves for precise control and automation.
- Available in modulating or on/off configurations, providing flexibility for different operational needs.
6. Seals and Gaskets:
- High-quality seals and gaskets ensure leak-proof operation and resistance to wear and tear.
- Compatible with a wide range of temperatures and pressures.
Working Principle
The Electric Lining Butterfly Valve operates on a simple yet highly effective mechanism:
1. Open Position:
- When the electric actuator is activated, it rotates the stem and disc by 90 degrees.
- The disc aligns parallel to the flow direction, allowing media to pass through with minimal resistance.
2. Closed Position:
- When the actuator rotates the stem back by 90 degrees, the disc turns perpendicular to the flow, blocking the passage.
- The resilient seat ensures a tight seal, preventing leakage.
3. Flow Regulation:
- By partially rotating the disc, the valve can modulate flow, providing precise control for applications requiring variable flow rates.
