This valve is the largest displacement valve that Forge currently produce. The unique design features a 50mm (2”) aluminium piston (meaning no issues with split diaphragms). As we endeavour to continue our innovation, existing products are no exception. Therefore, we have now released the all new version of “FMDVRAY.” It has been difficult to improve upon this market leading design, but we have done just that. We run this valve on our very own Mk1 race car, that's how confident we are in the product!

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
