Product environment

Sécheron’s BSV safety device is installed in the pneumatic circuit supplying air to any pneumatically-driven device. Before maintenance work, the BSV is manually switched off, interrupting the air supply and releasing the air pressure in the circuit. In the safe or “off” position, removing the interlocking key prevents the BSV from being unsafely switched back on, protecting maintenance workers.

For example, when maintenance technicians must work on or near high-voltage equipment, the BSV ensures that the pantograph cannot be raised during maintenance. The BSV can be delivered with other Sécheron safety key interlocking devices (earthing switches, key multipliers, door locks), as well as with other Sécheron components and solutions that guarantee the high-voltage electrical safety of the traction chain on AC or/and DC railway vehicles.

All of our components and solutions are backed by Sécheron expert service during all phases of your project. Let us recommend the best solution to meet your needs. Whatever your choice, you can count on efficient support worldwide for the entire lifetime of your product.
