Butterfly Valves Export | Wafer & Double Flange Types at Best Prices
- Butterfly valves are essential components in water supply, wastewater, industrial, and irrigation systems due to their compact design, durability, and cost-effectiveness.
- We supply two main types: Wafer Type (DN50–200, PN6–16) and Double Flange Type (DN100–3000, PN6–40), both designed for on/off service up to 70°C.
- Each valve is manufactured under strict DIN, ISO, and ANSI standards, with epoxy coatings certified for potable water use.
- Wafer type valves are lightweight, easy to install, and ideal for small to medium pipelines, while double flange valves are heavy-duty and suited for large-scale, high-pressure projects.
- Both models are competitively priced for export markets, with spare parts availability, actuator options, and long-term reliability.
