Description

Forge Motorsport - Twin Piston Blow Off Valve with Side Vacuum Nipple (Alloy finish)This version of our popular FMDV004 valve has the vacuum connection on the side of the valve which is ideal for those applications where space is restricted. Made from billet aluminum, this atmospheric diverter valve dumps the charge air to atmosphere creating the "Whoosh" sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike single piston or diaphragm

This version of our popular FMDV004 valve has the vacuum connection on the side of the valve which is ideal for those applications where space is restricted.    

Made from billet aluminum, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.

Fitment Guide: Suitable for most turbo cars with an Air Flow Meter. Dual-Piston Atmospheric Valves and Valve Fitting Kits

All Forge Motorsport Dual-Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift. While we have incorporated many elements into the design of the Dual-Piston valves to aid in their compatibility with mass air-flow sensor equipped vehicles, we cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.

Forge Motorsport nor any of it’s Authorized Distributors can assume any responsibility for any adverse effects resulting from the installation of this valve onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of compensating for the loss of metered air through a vent-to-atmosphere valve such as this.

 Please contact us if you are unsure whether this product is suitable for your vehicle.

In The Box:
1 x FMDV004A Valve
1 x Forge Sticker

The valve has a port size of 25mm

Cute & Tough
Pattern Name: Duck
Great toy! Both of my golden doodles love this duck. It’s been over a month and they haven’t even broken a seam.

Not indestructible
Pattern Name: Duck
I got this for my little dog hoping that she would not destroyed it but in a few days it was destroyed. I give it three stars because it only took my dog three days to destroy this completely.

Price and quality are excellent
I appreciate the price and amount I get, I included one of this toys in each of the puppies bags for when they go home with their new family. They are strong, feel and looks of good quality. I can't speak for their durability, my puppies are Yorkie and in the majority of the cases this toy is bigger than our puppies. They arrive fast and they are better than we expected.

Perfect Stuffed Animal
Bought these as a gift for our dog and he absolutely loves them! We haven’t even given him all of them yet because they’ve held up so well. Normally he destroys stuffed toys almost immediately, but these are surprisingly durable and have lasted much longer than expected. The only thing he seems determined to chew off are the ears — apparently he has something against stuffed animal ears 😂 Luckily my fiancé just cuts them off before giving the toys to him and they’ve been great after that!

Bad squeakers
These toys are so cute, but they come vacuum sealed, so all the squeakers were out of air and broken. These are unusable.
