263 Breather Valve
Working principle:
During operation, water systems and the water itself release gases when heated. If these gases are not promptly vented, they can lead to numerous adverse consequences. For example, in pressurized heating systems—such as district heating networks and solar‑thermal systems—these gases may accumulate and cause issues.
Pump systems, central air conditioning, boilers, and more.
Valve features:
Reliable performance: each valve undergoes rigorous venting and pressure‑sealing tests before leaving the factory, and every individual component is produced by lost‑wax precision casting, ensuring perfect assembly. The valve interior features a specialized steam–water separation design that prevents leakage during venting.
When the system generates a vacuum, it automatically opens to draw in air, preventing negative pressure and ensuring the safety of the system’s equipment.
