Constant Pressure Relief Valve
CONSTANT SET POINT / PRESSURE RELIEF
Constant Pressure Relief Valve
Constant Pressure Relief Valve is a mechanical safety component designed for positive pressure CBRN systems operating in accordance with NATO AEP-54 requirements. The valve automatically discharges excess internal pressure at a predefined constant set point to support stable overpressure conditions within sealed and protected environments.
Spring-based mechanical pressure-relief architecture calibrated to a fixed opening threshold for automatic overpressure regulation.
Automatic Pressure Relief at a Predefined Constant Set Point
The Constant Pressure Relief Valve is used to automatically limit internal pressure by releasing excess air when pressure reaches a fixed threshold.
Unlike adjustable pressure-relief designs, the valve operates at a predefined pressure set point and does not require manual pressure adjustment during normal operation. This supports repeatable overpressure control while limiting continuous pressure buildup within the protected CBRN system.
Continuous Overpressure Control for Protected CBRN Environments
The valve is deployed in positive pressure CBRN systems installed in military vehicles, armored platforms, shelters and protected enclosures.
It is suited to applications requiring continuous overpressure regulation as part of a sealed collective protection architecture intended to reduce ingress of contaminated external air.
Set Point FIXED
Spring-Based Constant Opening Pressure
The valve uses a spring-based mechanical structure calibrated to a constant opening pressure. When internal pressure exceeds the predefined level, the valve opens automatically and discharges excess clean air.
Once the internal pressure returns to the set level, the valve closes automatically. This operating principle supports continuous pressure regulation without manual intervention during system use.

Operational Applications
Constant Overpressure Regulation Without Manual Intervention
The valve maintains the specified constant internal overpressure condition by automatically releasing excess air generated by the CBRN filtration system when pressure rises above the fixed set point.
Controlled discharge limits pressure buildup while supporting the positive pressure barrier used by the collective protection system to reduce ingress of contaminated external air.

Frequently Asked Questions
01 What is the function of a Constant Pressure Relief Valve in CBRN systems?
It automatically releases excess internal pressure to maintain a fixed overpressure level in positive pressure CBRN systems.
02 How does a constant pressure relief valve differ from an adjustable valve?
The constant pressure valve operates at a predefined pressure set point and does not require manual pressure adjustment during operation.
03 Where is the valve typically installed?
It is installed in sealed military vehicles, armored platforms, shelters and protected enclosures equipped with positive pressure CBRN filtration systems.
04 Does the valve operate automatically during system use?
Yes. The valve opens automatically when internal pressure exceeds the fixed threshold and closes once pressure returns to the set level.
05 Can the valve be manufactured in special dimensions?
Yes. The supplied product information states that the valve can be produced in custom dimensions according to platform or user-specific requirements.
