Electric Plastic Anti‑corrosion Butterfly Valve
The UPVC Electric Butterfly Valve delivers automated flow control for corrosive chemical and industrial service. Its corrosion-resistant, lightweight body resists alkalis and solvents, while the integrated electric actuator provides precise ON/OFF or modulating control. Ideal for water treatment, chemical plants, and effluent systems requiring dependable performance in aggressive environments.
特点
- Hygienic & certified — Non-toxic, food-safe material compliant with drinking-water hygiene standards.
- Low maintenance — Abrasion-resistant and easy to service; suited to a wide range of applications.
- Lightweight — UPVC weighs about one-tenth of cast iron, reducing handling, installation, and cost.
- Chemical resistance — Strong acid/alkali resistance extends service life beyond conventional piping.
- Fire-safe — Self-extinguishing and non-combustible; eliminates fire-risk concerns.
- Durable & efficient — High strength and toughness with a smooth bore that resists fouling and minimizes pressure loss.
