Description
Product Description
We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
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!
Highlights:
- Improved external aesthetics
- Utilising world leading Eibach springs for more precise operation and consistency
- A myriad of incremental engineering enhancements to all internal components have been carried out to offer faster response times and longer service intervals
- The piston uses heat stabilised Viton O-rings
- Lubricated with high temperature Mobil1 grease to ensure a long life with minimal wear and very long service intervals
- A super durable and responsive aluminium piston
- A fully serviceable valve that is rebuildable in minutes
- Available in anodised black or anodised purple
- Ideal for custom installations using the aluminium weld on coupler and clamp provided
- Covered by the unique Forge Lifetime Warranty*

Warranty
10 Year Warranty Information
The majority of Forge Motorsport products come with a limited 10 Year Warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.
For further information, please call our customer service team on +49(0)3222/1097-308 or email info@forgemotorsport.eu.
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.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.

Expert Answers
Do I need to use an O'ring with this dump valve? I note there isn't one in the kit.
No O ring seal is required at the connection to the weld on boss adaptor; 100% seal is achieved upon fixing into position using the provided clamp.
