Belmit Development’s
Water Re-circulation Valve
The Hottest and Coolest new product in racing

Have you ever lost a race or blown a motor because you put too much tape on the radiator and had no way to remove it? Have you not been able to get heat into your engine on really cold nights? If these problems have happened to you, then we have the Solution. The Belmit water re-circulation valve lets the driver control how much water flows into the radiator and how much bypasses the radiator and is recycled back into the engine. This valve is not a thermostat. Thermostats have been tried for years but they often stick or when they do work they thermally shock the engine as they open or close. The Belmit re-circulation valve is completely driver adjustable and will not shock your engine. The valve will still allow 100% water flow as normal with no cavitation to the engine even when the flow to the radiator has been completely shut off! The best part of all, you will no longer have to guess on how much tape to use for building heat.
