High-speed breathing valves (also known as High velocity Pressure/Vacuum valve) are one of the cargo tunnel ventilation devices to ensure the balance of vapor pressure inside the cargo hold, avoiding mechanical deformation of the cargo hold when the internal pressure changes by temperature or any other cause.
2-way breathing valve with high motority, open the suction door when low pressure, open the exhaust door when high pressure automatically. Do not require any manual action from the user.
