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

Overpressure exhaust valves are primarily used for protective engineering exhaust outlets, which are normally in a closed state. When filter-toxic ventilation is required, it is necessary to construct

Maintain a pressure differential of 30-50 Pa, at which point the valve cover of the活门 (gate valve) will automatically open under the effect of the overpressure to expel toxic gases from the anti-toxic passage. When war needs...

During the isolation protection process, manually secure the valve cover, at which point the swing gate has the protective airtight function. This device can directly replace the war-time exhaust system on

The explosion-proof baffle and automatic exhaust valve assembly, which forms the exhaust and wave-dissipation system, is normally in an open position for easy exhaust; 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 connection through a custom flanged pipe reducer; equipment installation

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