The overpressure exhaust valve features a simple structure, attractive design, advanced technology, and reliable performance, making it an indispensable protective equipment for the filter-toxin ventilation system in protective engineering.

Overpressure exhaust valves are mainly used for the exhaust outlets of protective engineering, which are normally in a closed state. When decontamination ventilation is required, the internal space of the project must be...

Maintain a pressure differential of 30-50 Pa, at which point the valve cover of the regulating gate will automatically open under the influence of the overpressure to expel the toxic gas from the decontamination passage. When wartime requirements

During the operation of isolation protection, manually tighten the valve cover. At this point, the gate valve has the function of airtight protection. This device can directly replace the ventilation system during wartime.

The explosion-proof flap and automatic exhaust valve-composed exhaust and wave attenuation system is normally in an open position for easy ventilation; under the positive pressure of shock waves,

The valve cover automatically closes, reducing over 90% of the shock wave energy; this differential pressure exhaust valve requires a custom reducer pipe flange connection for equipment installation.

The connected pre-buried pipe flange thickness is 8mm, and a gasket must be used for the valve's seal with the pre-buried pipe.
