Explosion-proof open valves, 9 bars, type Z.

BVNO explosion-proof valves: protection against hazards.
Explosion-proof valves are the main protective devices that remain open under normal conditions, allowing air to flow freely in and out of the protected space. These innovative solutions are therefore installed on vents and ducts in ventilation systems. Their main purpose is to protect shelter spaces and structures against blast-induced pressure waves, which can be both positive and negative. Thanks to these devices, you can reduce the risk of damage and ensure the safety of those inside the protected premises.

BVNO explosion-proof valve models.
We offer a range of BVNO explosion-proof valve models tailored to different needs and specifications. For example, you can use the following options to choose the right model:

BVNO 50 - nominal air flow: 50 m³/h at 200 Pa
BVNO 550 – nominal air flow: 550 m³/h at 200 Pa
BVNO 600 – nominal air flow: 600 m³/h at 200 Pa
BVNO 1000 – nominal air flow: 1000 m³/h at 200 Pa
BVNO 1800 – nominal air flow: 1800 m³/h at 200 Pa
BVNO 2600 – nominal air flow: 2600 m³/h at 200 Pa
BVNO 2900 – nominal air flow: 2900 m³/h at 200 Pa

Each model has different characteristics that allow them to be optimally adapted to the specific application.

Technical specifications for BVNO valves.
Our BVNO explosion-proof valves have a high resistance to various factors. Here are the main technical specifications.

Back pressure resistance: >900 kPa (9 bars)
Mechanical impact resistance: >12 g

This applies to the Y version, which is equipped with a safety feature that further increases its efficiency.

Adapting valves to individual customer needs
BVNO explosion-proof valves can be easily customised to meet customer needs, we offer various options such as:

Enclosures for ducted connection
Apkakles
Pre-filters
Quick connectors

This allows the specific requirements of each project to be met efficiently.

These valves are used in a wide range of industries where safety and explosion protection are a priority. For example, we offer solutions suitable for the chemical, petrochemical and other industries exposed to potential threats.
