Forge Motorsport Valve Service Kit

For info on how to service your valve, click on the 'Instructions' tab above or visit Forge Motorsport guides here

To order the correct part, you will need to the know the Forge product code of your valve. This will start with 'FM' and will be located on your original purchase receipt, or on the side of the product box. By servicing your valve/adaptor at regular intervals, you can ensure that your Forge Motorsport product will last a lifetime.

Each service kit varies depending on which product you need it for: 

  • Valve service kits ONLY contain replacement "O" rings, piston, and grease. 
  • Blow off adaptor service kits contain ONLY replacement "O" rings and bolts. 
  • The splitter valve service kit contains a replacement brass piston and spring.   
  • Valves that have O-rings situated on the piston will not come with a piston as the wear is on the O-rings rather than the piston itself.

Forge 34mm Split Recirculation and Blow Off Valve

Forge

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes soonerThe Splitter is a truly remarkable valve that gives a combination of blow off and recirculation valve operation all at the same time and has been specifically designed for the many turbo engined applications that operate metered airflow management sysyems. This means you get all the noise of the blow off valve whilst retaining the compatibility with the recirculation requirements of the engine management system. As a bonus we also offer the ability to convert the valve to recirculation only mode for those times when stealth running is required.This valve uses a Brass piston which utilises new sealing technology along with a variable spring preload incorporating a ratchet type top adjuster that will allow for the positive and precise adjustment to match the valve to your engine. This is achieved by using a unique single, conical, progressive rate spring that can allow for the retention of boost pressure over a wide adjustment range. This unique spring design also allows for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring. Other manufacturers valves using cylindrical springs with adjustable pre-load often experience restricted piston travel and a reduction in flow volume.This valve has 34mm pipe connections. In The Box:1 x FMBSPLTR Valve1 x Valve Blanking Cap1 x 500mm of 4mm Vacuum Tube1 x Instructions1 x Forge Sticker To service this valve, access the valve piston by removing the 3 cap screws at the base of the valve and simply clean the piston chamber using brake cleaner or similar cleaning fluid before installing the new spring and piston. Please observe the correct spring and piston orientation when installing the serviceable parts, as seen in the attached drawing.

Forge Blow Off Valve for VW, Audi, Seat & Skoda 1.5 TSI

Forge

The Forge Motorsport FMDV22 Blow off valve kit now fits all engine variants, please identify from the images below whether you require the extra breather adapter for you application.We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes soonerIf your engine bay is the same as shown above then you will require the aditional breather adapter so please make sure to select 'Yes' on the Breather adapter dropdown option.If your engine bay is the same as shown above you do not require the additional breather adapter, please make sure to select 'No' on the dropdown option.As the engine does not have a diverter valve fitted as standard, Forge have developed a twin piston dump valve that not only gives you an incredibly loud sound when lifting off the throttle, but also increases the throttle response during gear changes by reducing turbo lag. It has been designed to help the turbocharger maintain its rotational speed ready for when you accelerate, whilst also taking the strain away from the impeller. Without removing this stress from your turbo, it could cause premature failure. Especially on engines and modified vehicles.This valve kit allows the fitment of our fast response blow off valve preventing turbo surge and prolonging the life of your engine’s turbocharger. The kit includes all of the necessary hardware and step by step installation instructions for any car enthusiast with appropriate garage tools to fit at home, in just a couple of hours! Due to the exposed position of the OEM boost pipe and the nature of heat cycle, the plastic that the OEM pipe is made from can deteriorate over time, becoming brittle and susceptible to boost leaks. This kit totally replaces this plastic pipe from turbo to manifold with a silicone hose (available in a choice of colours!). Highlights: CNC machined billet couplers and components CNC machined twin piston Forge valveThree hose options: red, blue, or black (Custom available but will incur a 50% non-refundable deposit and a lead time of 8-10 weeks)Forge valve will not bring on any check engine lights (EML) The hose has a quality inner lining of modified silicone known as 'Fluorosilicone'. This means that the hose will stay bright and vibrant, and will not deteriorate over time. Forge Motorsport lined hoses are suitable to be used with modern long-life coolants, Organic Acid Technology coolants (O.A.T.) and oil mist. The construction of the hose has been engineered to exceed that of the OEM fitments, the Forge Motorsport hose will enhance any engine bay both technically and aesthetically.The hose from this kit replaces OEM part numbers 05E.145.673.E and 05E.145.674.EWe cannot guarantee that this product will fit with all aftermarket intakes.Lifetime warranty.In the Box:1 x Atmospheric Dump Valve1 x Boost Tap/Take Off (Including Cork Gasket and Screws) Throttle Body and Turbo Couplers1 x Silicone Hose (Red, Blue or Black)3 x Hose ClampsAll fixings and fittings1 x Roll of Vacuum Tubing1 x Wiring Loom Extension1 x Forge Sticker

Forge Dual Piston Blow Off/Dump Valve

Forge

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes soonerSuitable for most turbo cars with an Air Flow Meter. Made from billet aluminium, 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.Please note if you are purchasing this valve for a Fiat Punto 1.4 93-99 you will also need a fitting kit which can be purchased here.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 Authorised 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.
