The super pressure exhaust valve features a simple structure, attractive design, advanced technology, and reliable function, making it an indispensable protective device 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 filter-toxin ventilation 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 war needs arise

When applying isolation protection, manually secure the valve cover, at which point the valve has a protective airtight function. 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 the 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 connection via a custom size reducer pipe flange for 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.
