Adjustable Pressure Relief Valve
Adjustable Pressure Relief Valve
Adjustable Pressure Relief Valve is a mechanical safety component designed for positive pressure CBRN systems operating in accordance with NATO AEP54 standards. The valve is used to discharge excess internal pressure in a controlled manner, ensuring stable overpressure conditions within sealed vehicles or protected enclosures.
Adjustable Pressure Relief Valve
Adjustable Pressure Relief Valve is designed to limit and regulate internal pressure levels in positive pressure CBRN systems. When internal pressure exceeds the predefined threshold, the valve opens to release excess air, preventing structural stress and maintaining the required pressure balance for effective CBRN protection.
Deployment Areas
The valve is deployed in positive pressure CBRN systems used in military vehicles, armored platforms, shelters, and protected cabins. It is suitable for applications where hermetically sealed environments are required and controlled overpressure must be maintained to prevent external contamination.
Design and Adjustment Structure
The valve is based on a spring-loaded mechanical structure that allows adjustment to the required pressure level. Opening pressure can be set according to system specifications, enabling precise control of overpressure discharge.
Adjustable Pressure Relief Valves can be manufactured in standard or custom dimensions based on user requirements. The design supports continuous airflow discharge under proper operating conditions, ensuring pressure stabilization without interrupting system operation.
Test Standards
Adjustable Pressure Relief Valves for CBRN systems are designed and validated in line with applicable military and industrial standards, including NATO AEP54 requirements for collective protection systems. Environmental durability is verified through high temperature, low temperature, humidity, corrosion, shock, and vibration testing in accordance with relevant MIL-STD-810 test methods.
Functional Role
The valve maintains a stable internal overpressure by automatically releasing excess clean air generated by the CBRN filtration system. This controlled discharge prevents pressure buildup while ensuring that positive internal pressure continuously blocks the ingress of contaminated external air, preserving the integrity of the protected environment.
