7100 Emergency Pressure Relief  Valve

Product Overview

7100 Emergency Pressure Relief Valve is used to overpressure conditions that can not be handled by standard venting hole,the discharge capacity meets API2000 standard and is sufficient to cope with emergency evacuation needs caused by fire,it can also be used as an inlet and outlet for inspection and  maintenance.
7100 emergency pressure relief valve is used for release overpressure,no inhalation function. When the pressure in the tank rises to the set pressure, the hinged cover opens to release the pressure, and when the overpressure phenomenon dissipates, the hinged cover returns. The hinge mechanism ensures accurate resetting of the hinge cover.


Certifications

BasCo emergency relief valves are designed and manufactured strictly in accordance with international and domestic standards such as API2000, ISO28300, GB/T, and have obtained qualification certifications such as EAC, DNV, and explosion-proof certificates.
