LH/AD-T

After the flame is detected, a secondary measure, such as inerting Inerting Replacing atmospheric oxygen in a plant with a non-reactive, non-flammable gas to prevent flame propagation in the atmosphere of a plant. or closing of a shut-off valve Shut-off valve A shut-off valve is used for controlled opening and closing of pipes. In closed position, the valve does not allow flow in any direction. to block the vapor flow to the device, should activate within 60 seconds and extinguish the flame so that the system can operate safely. The device prevents flame transmission from short time burning and atmospheric deflagration into the vessel Vessel Container or structural envelope in which materials are processed, treated or stored. or plant.
