Explosive safety valve with fire barrier VPKO
An explosive safety valve with a fire barrier In the PKO is designed to relieve pressure in the protected equipment, extinguish the flame and air wave formed during the ignition or explosion of a gas-air mixture inside the equipment.
It is the ability of the valve to quickly close the outlet that is its main advantage. It ensures rapid sealing of the equipment and the absence of fresh air, which can lead to the formation of a new explosive mixture and repeated explosions in the protected equipment. Rapid sealing also increases the time of equipment shutdown, which is important in an emergency situation to make a decision or the complete absence of equipment shutdown.
