FM Approvals has been made aware of counterfeit air vents (release valves) found in Thailand bearing the FM Approvals’ certification mark. FM Approvals has neither tested nor certified these products.

Description: Air Release Valve
Make/Model: MVC15
Nameplate Data: 175 P.S.I. C.W.P.

FM Approval Status: Not FM Approved.

Hazard Involved: These air release valves cannot be relied on to operate as intended. Air release valves expel air or gas up to the full operating pressure of the fire protection system.
