PIAA Radiator Valve
[Regular type]
Prevents overheating/improves cooling effect for engine comfort
The radiator valve is a cooling system that prevents power down and ensures responsive and stable power even in extreme conditions such as long periods of time driving with a high rotation range of high power engines. Radiator valves play a very important role in this system.
The resin radiator valve uses two valves, including the main pressure valve (pressure valve) and negative pressure valve, so the pressure within the cooling system is properly applied, and the product itself is not the same as conventional radiator valves.
The difference is that it is stored on top of the reservoir tank, so only air in the reservoir tank passes through the radiator valve and regulates the pressure.
The combustion of the engine increases the temperature inside the cooling system and the volume of the coolant water expands to increase the volume of the coolant in the reservoir and the air is pumped.
When the pressure is above the prescribed pressure (main pressure valve) opens to adjust the pressure by allowing air to flow during standby. Conversely, when the engine cools down and the temperature inside the cooling system is lower, the pressure pressure pressure will also be reduced.
At this time, negative pressure valve activates and suck air back from the atmosphere, preventing negative pressure in the cooling system.
