Product Overview

The 5100 End of Line Breather Valve maintains a sealed state.When the system pressure or vacuum exceeds the valve setting value, the valve core is lifted, the sealing state between the valve seat and the valve core is broken, and the pressure or vacuum accumulation is released. Once the release is completed, the valve remains sealed again.

Installation location: Connect the tank through the flange, and the valve is directly discharged to the atmosphere after opening.

Certifications
BasCo pressure vacuum relief valve are designed in accordance with international and domestic standards including SY/T0511 and API 2000-2020, and have obtained qualification certifications such as ATEX, EAC, DNV, TS, CCS and Type Test Certificate.
