The superpressure 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, remaining closed under normal conditions. When filter ventilation is required for decontamination, the internal spaces of the engineering must be...

Maintain a superpressure of 30-50 Pa, at which point the valve cover of the actuator opens automatically under the influence of the superpressure to expel toxic gas from the decontamination passage. When wartime requirements dictate...

During the isolation protection, manually secure the valve cover, at which point the valve door has the function of protective airtightness. This device can directly replace the ventilation system during wartime.

The explosion-proof wave dampening valve and automatic exhaust valve-composed exhaust and wave damping system is normally in an open state 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.
