The Explosion Protection Valve ESV 3 (GP) is a pressure-resistant exhaust air valve designed for protective shelter ventilation systems. It safely exhausts stale air from the shelter while protecting occupants and critical infrastructure against pressure and suction waves caused by conventional and nuclear explosions.
Designed for basic protection (1 bar), the valve complies with the requirements of Technical Specification TPH 04issued by the Swiss Federal Office for Civil Protection (BABS). It is suitable for use in civil, military, and industrial protective facilities where reliable blast protection is required.

Explosion Protection Valve ESV 3 (GP) – Exhaust Air Valve for Safe Room Ventilation Systems
The ESV 3 (GP) Explosion Protection Valve is a pressure-resistant exhaust air valve designed for safe room ventilation systems. It ensures the controlled removal of used air from protected rooms while providing reliable protection for people and technical equipment against the effects of pressure and suction waves caused by conventional and nuclear explosions.
The valve was specifically developed for use in protected environments and ensures reliable operation even under extreme load conditions. Thanks to its automatic closing function, the airflow is safely interrupted when pressure waves occur.
The ESV 3 (GP) is suitable for civil protection facilities, military protection systems, and safety-critical industrial applications.
Application and Areas of Use
The ESV 3 (GP) Explosion Protection Valve is used as an exhaust air valve for safe room ventilation systems.
Typical applications include:
- Civil protection facilities
- Personnel protection rooms
- Military protection facilities
- Critical infrastructure
- Command and communication facilities
- Industrial safety areas
The valve provides a pressure-resistant closure for exhaust air openings and supports the overall protection function of the ventilation system.
Function and Operating Principle
During normal ventilation operation, the ESV 3 (GP) allows the controlled removal of used air from the protected room.
In the event of a pressure wave, the valve disc is automatically pressed against the sealing surface. This closes the airflow passage within a very short time and prevents dangerous pressure forces from entering the protected area.
The valve also reacts reliably to the suction effect following an explosion and closes in the opposite direction.
After the pressure or suction phase has ended, the valve automatically returns to normal operating conditions.
Construction and Design
The ESV 3 (GP) is manufactured with a robust, corrosion-protected design and is developed for long-term operation in protected facilities.
