Condensation-Proof Aluminum Alloy Lever Butterfly Valve
This is a specialized lightweight butterfly valve designed for general utility applications, particularly in environments susceptible to condensation. The use of an Aluminum Alloy body with specific material properties effectively prevents the formation of condensation (dew) on the valve body, actuator, and flanges.

✨ Anti-Condensation and Material Advantages
The core benefit of this valve lies in its body material composition, which addresses the issue of condensation often found in HVAC, chilled water, or cooling systems:
- Anti-Condensation Feature: The high-performance Aluminum Alloy body effectively minimizes the temperature differential across the valve body, successfully preventing condensation from forming on the actuator and flange surfaces.
- Superior Body Material: The Aluminum Alloy offers properties four times better than common materials in terms of:
- Low Water Absorption
- Corrosion Resistance
- Insulation/Cold Barrier
- Reliable Sealing: The valve seat uses standard-compliant EPDM or NBR rubber, ensuring excellent elasticity and tensile strength. Guaranteed zero leakage after over 10,000 open/close cycles.
- High-Quality Disc: The disc (valve plate) is constructed from Stainless Steel 304, meeting mechanical and anti-corrosion performance standards.
- Packaging: Utilizes an PE heat-shrink plastic sealing process (similar to electronic products) for individual packaging, including desiccant, to isolate moisture and prevent corrosion during storage.
