Product Information

SPAC radiator valves

  • Overheating prevention
  • Good condition engine with cooled
  • Prevent the hot water balloon accident

SPAC radiator valve is just a lid is not.
High rpm high performance high power engine, diversity does not have the cooling system to ensure power and its responses to stable, long even in extremely harsh conditions, such as driving down to prevent.
In this system plays a very important role SPAC radiator valves.

Cooling system the cooling effects to extreme levels.

The engine around cooling cooling water circulating cooling and internal combustion engines, high temperature and became by the radiator cooling system.
Radiator inside the at higher pressure than atmospheric pressure (98 kPa) SPAC radiator valves are.
Why is the radiator cooling (heat capacity) is proportional to the difference between the temperature of the cooling water from.
Is the bigger the higher the temperature of the cooling water radiators heat transfer capacity.
So we won't let boiling cooling water to boil at 100 ° c in atmospheric pressure if SPAC radiator valve radiator internal pressure to increase temperature of 120 ° c or up to.
As a result, dramatically increases radiator heat dissipation capacity is the very large temperature difference between the air.
And cooling system cooling effect is increased to the limit.

■ internal pressure radiator and cooling water boiling temperature
On the Earth there originally 1 ATM (98 kPa).
Since 98 kPa is SPAC radiator valve pressure valve pressure 1 ATM 98kPa+88pKa = 186 kPa the
Actual working pressure.

* Also some 108 kPa products

The cooling effect of the cooling system maintained perfectly.

SPAC radiator valves always keep proper pressure inside of the radiator required for main pressure valve springs to enhance the cooling system works best.
Along with the rise in internal temperature, high pressure and pressure to adjust the main pressure valve work.
Also, along with lowering the inside temperature low pressure and negative pressure valve and work, adjust the pressure.
Each function inside of the radiator pressure always restore to the proper state.
This result can be to keep the best cooling effect of the cooling system, engine high performance and high power up to perfection.

Upon opening the faucet hot water venting desensitization to prevent perfect safety button

Open plug during decompression is realized.
Occupy the main rate could result in overheating radiator caps of well known recently became the owner driver course in gas stations and maintenance workshops check valves frequently as now is made, as a result, we have become increasingly hot water balloon accident upon opening the faucet.
So PIAA has developed safety button to allow decompression when the CAP is opened.
This one-touch anyone easily and safe and efficient maintenance and inspection enabled.

PIAA DIGITAL BOOK, and apply search is possible under the RADIATOR VALVE.

初めて社外製ラジエータキャップに交換
Posted by たま**** , 2014/06/19 06:44:59
純正志向が強くこれまでは車検や点検時にしか変えたことがありませんでしたが、 今回初めて変えてみました。減圧出来るプッシュボタン付きとなるとこの商品が一番のような気がいたします。所有する車2台とも交換しました。
ドレスアップに

過去にトヨタbBの車に使用してました。 実際、ボタンを使ってみたことはありませんが、 エンジンのドレスアップ的な要素が強いです。

純正よりロゴが感じ良い。レギュラー仕様なので安心出来る。
