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

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

Maintain a superpressure of 30-50 Pa, at which point the valve cover of the actuator opens automatically under the effect of the superpressure to expel toxic gas from the anti-toxic passage. When wartime needs arise...

During the process of using the valve cover to isolate protection, manually tighten the cover, at which point the valve door has the function of protective airtightness. This device can directly replace the exhaust system during wartime.

The explosion-proof relief valve and automatic exhaust valve组成的air 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 shock wave energy; this differential pressure exhaust valve requires connection through a custom flanged reducer pipe, equipment installation

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