A butterfly valve is a manual flow control device widely used in drip irrigation systems to start, stop, or regulate the flow of water in mainlines or sub-mainlines.
It consists of a disc-shaped closing mechanism that rotates around a central shaft. When the valve handle is turned, the disc either blocks the flow (closed) or aligns with the flow (open), allowing precise control of water delivery.
Key Features:
- Material: Generally made of high-quality PVC, polypropylene, or HDPE, which are corrosion-resistant and suitable for agricultural use.
- Operation: Quarter-turn handle (90° rotation) for quick on/off or flow adjustment.
- Pressure Rating: Typically designed for low to medium pressures, ideal for drip systems (e.g., up to 2.5 to 6 kg/cm²).
- Connection Type: Available with flanged, threaded, or plain ends for easy installation in irrigation pipelines.
- On mainlines and sub-mainlines to control water supply to different blocks
- Used at the inlet of filters, venturi injectors, or tanks
- Ideal for greenhouses, nurseries, orchards, and open field drip systems
- Simple to operate and maintain
- Ensures efficient water management
- Durable for field conditions
- Allows section-wise control of irrigation zones
