The super-pressured exhaust valve has a simple structure, an aesthetically pleasing design, advanced technology, reliable function, and is an indispensable protective equipment for the filter-toxin ventilation system in protective engineering.

Overpressure exhaust valves are primarily used for the exhaust outlets of protective engineering, remaining in a closed state during normal operations. When filtration and ventilation for decontamination is required, the internal structure of the project must be...

Establish and maintain a pressure differential of 30-50Pa, at which point the valve cover of the actuator will automatically open under the influence of the overpressure to expel the toxic gas from the anti-toxic passage. When war is needed

When implementing line isolation protection, manually secure the valve cover, at which point the gate valve has the function of protective airtightness. This device can directly replace the wartime exhaust system on

The explosion-proof baffle and automatic exhaust valve assembly forms an exhaust and wave-dissipation system, which is in an open state during normal operation 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 via 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.
