Wafer Butterfly Valve with Worm Gear Actuator：
Shop high-quality wafer butterfly valves with worm gear operation. PN16 rated, cast iron body, EPDM/NBR seal. Ideal for water, HVAC, and industrial systems in USA and Canada.
🔹 Product Introduction
Our Wafer Butterfly Valve with Worm Gear Actuator is designed for reliable flow control in water, HVAC, and general industrial applications across North America. Built with a robust cast iron body and precision-engineered EPDM/NBR soft seal, this PN16-rated valve delivers tight shut-off, corrosion resistance, and long service life. It features a wafer-style connection for compact installation, making it ideal for space-constrained piping systems in the USA and Canada.
🔹 Core Features
01. Reliable Technology
✅ Built-in Overheat Protection: Prevents actuator burn-out during prolonged operation, ensuring stable performance in continuous-duty systems.
✅ Durable Alloy Housing: The corrosion-resistant cast iron body with anti-rust coating provides excellent wear resistance, suitable for harsh industrial and outdoor environments.
✅ Bubble-Tight Shut-Off: The precision-machined disc and soft seal ensure zero leakage, meeting ANSI Class 150 sealing standards.
02. Superior Operation
✅ Waterproof & Rust-Proof Construction: Sealed actuator housing and anti-corrosion treatment prevent water ingress and rust, ideal for humid or outdoor applications.
✅ Worm Gear Actuation: Low-torque, smooth operation with self-locking function to prevent accidental disc movement, ensuring system safety.
✅ Easy Installation & Maintenance: Wafer-style design fits between standard flanges, requiring minimal space and no additional gaskets for quick setup.
03. Premium Body Quality
✅ Precision Cast Iron Body: Made from high-grade cast iron with precision casting technology, ensuring uniform wall thickness and structural integrity.
✅ High-Temperature Resistant Materials: Compatible with operating temperatures up to 120°C (248°F), suitable for HVAC hot water and industrial process systems.
✅ Fine Workmanship: CNC-machined sealing surfaces and smooth coating finish prevent media buildup and extend the valve’s service life.
