The superpressure exhaust valve features a simple structure, attractive design, advanced technology, and reliable functionality, making it an indispensable protective equipment for filter-toxin ventilation systems in protective engineering.

Overpressure exhaust valves are mainly used for the exhaust outlets of protective engineering, remaining closed in normal operation. When filter毒 ventilation is required, the internal system of the project must be constructed.

Maintain a superpressure of 30-50Pa, 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 requirements dictate...

During the operation of isolating protection, manually secure the valve cover, at which point the valve has the function of protective airtightness. This device can directly replace the wartime exhaust system on

The pressure wave dampening system, consisting of a shockproof flap valve and an automatic exhaust valve, is in an open state under normal conditions 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 through a custom flanged pipe reducer; 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.
