The superpressure exhaust valve features a simple structure, attractive design, advanced technology, and reliable functionality, making it an indispensable protective device for the filter-toxic 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通风 is required, the interior of the project must be constructed

Maintain a pressure differential of 30-50 Pa, at which point the valve cover of the solenoid valve automatically opens under the action of the overpressure to expel the toxic gas from the decontamination channel. When wartime needs

When implementing isolation protection, manually secure the valve cover, at which point the valve has a protective airtight function. This device can directly replace the wartime exhaust system.

A shock wave attenuation system composed of a pressure relief valve and an automatic exhaust valve, which 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 a custom flanged pipe elbow connection for equipment installation.

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