Adjustable Pressure Relief Valve
PRESSURE RELIEF / MECHANICAL 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 AEP-54 requirements. The valve releases excess internal pressure in a controlled manner to support stable overpressure conditions within sealed vehicles and protected enclosures.
Adjustable mechanical pressure-relief architecture for controlled overpressure discharge in positive pressure CBRN systems.
Controlled Overpressure Regulation for CBRN Systems
The primary purpose of the Adjustable Pressure Relief Valve is to limit and regulate internal pressure in positive pressure CBRN systems. When pressure exceeds the predefined threshold, the valve opens to discharge excess air.
Controlled pressure relief helps prevent excessive pressure buildup while supporting the pressure balance required by sealed collective protection environments.
Positive Pressure Systems for Sealed Military Environments
The valve is deployed in positive pressure CBRN systems used in military vehicles, armored platforms, shelters and protected cabins.
It is intended for applications where hermetically sealed environments require controlled overpressure management as part of the system architecture used to reduce ingress of contaminated external air.
Mechanism SPRING
LOADED
Adjustable Mechanical Opening Pressure
The valve uses a spring-loaded mechanical structure that allows the opening pressure to be adjusted according to system requirements.
When internal pressure rises above the selected threshold, the valve opens automatically to release excess air. Once the pressure condition is stabilized, the valve closes, supporting controlled overpressure regulation without interrupting normal system operation.
Mechanical Pressure Regulation Features
Adjustable Opening Pressure
Opening pressure can be set according to the required positive pressure system specification.
Spring-Loaded Mechanism
A mechanical spring-loaded structure provides adjustable pressure-relief operation.
Automatic Pressure Relief
The valve opens automatically when internal pressure exceeds the configured threshold.
Pressure Stabilization
Controlled discharge supports stable overpressure conditions within the protected enclosure.

Operational Applications
Automatic Excess-Pressure Discharge
The valve supports stable internal overpressure by automatically releasing excess clean air generated within the CBRN filtration system when the selected pressure threshold is exceeded.
This controlled discharge limits pressure buildup while supporting the positive pressure condition used by the collective protection system to reduce ingress of contaminated external air.
