Built for demanding environments

Key advantages

Solid DZR & Heat-Resistant Polypropylene: Crafted from high-quality solid DZR (Dezincification Resistant) brass and heat-resistant polypropylene, these vents are built to last. Their durability ensures optimal performance even in demanding piping systems.
Resistant to Dezincification and Corrosion: The vents exhibit excellent resistance to dezincification and boast high general corrosion resistance, providing longevity and reliability.
Ease of Inspection and Cleaning: Designed for practicality, these vents can be easily disassembled for inspection and cleaning, ensuring they remain in top working condition.
High-Temperature Resistant Float: The float within the vents is constructed from high-temperature-resistant polyethylene, guaranteeing its effectiveness even in high-heat environments.
Impurities Resistant: These vents are engineered to maintain functionality, as impurities typically do not interfere. The maximum float line of water always remains below the valve seal.

Technical data

Maximum Working Pressure: The vents are rated to handle a maximum working pressure of 174 psi (12 bar), making them suitable for various applications.
Maximum Working Temperature: With a capability to operate reliably at temperatures up to 120ºC (248ºF), they are versatile and compatible with diverse environments.
Connection: Featuring male threaded connections, they seamlessly integrate into your existing system.
