Forge Universal Blow Off & Diverter Valves

Universal Twin piston Blow off valve with side vacuum nipple

R.R.P. £99.99

Only: £79.99

Suitable 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. 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.

Available in machined alloy or black finish.

Universal Piston Closed Loop Diverter Valve with Adjustable Vacuum Connection

R.R.P. £111.99

Only: £89.99

Suitable for most turbo cars with an Air Flow Meter

Made from billet aluminium, this recirculating diverter valve dumps the charge-air back into the air intake system keeping external noise to a minimum. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike diaphragm diverter valves, this uses counter balanced springs and a single piston 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.

Available in machined alloy or black finish.

Universal Piston Ram Dump Valve (With Filter)

R.R.P. £106.99

Only: £85.99

Suitable 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 most commonly associated with rally cars when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

For applications where the valve may be subject to dusty conditions a filter is used to prevent particals entering the valve. 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.

Universal Type RS Valve - Atmospheric

R.R.P. £197.99

Only: £157.99

The Forge RS valve has been specifically designed and engineered, to offer extreme flow rate capability, where other valves are just not up to it. Often when engines have been tuned by installing larger turbos or even software upgrades improved turbo response can be acheived by fitting the RS valve which has the greater internal mass air flow specification utilising an amazing 50mm (2") bore.

For fine tuning there is a variable spring preload incorporated and a ratchet type top adjuster that will allow for the positive and precise adjustment that your driving style demands. To ease installation a 360 degree adjustable vacuum hose connector With a choice of inlet and outlet connections the RS valve can be matched to your engine perfectly.

This valve incorporates a unique conical, progressive rate spring that can allow for the retention of boost pressure from 7 to 34 PSI depending on the individual user's application and level of adjustment.

This unique spring design will also allow 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 flow volume within the normal range of valve adjustment.

Universal Type RS Valve - Recirculating

Universal Splitter Recirculation & Blow Off Valve

R.R.P. £158.99

Only: £126.99

The 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 Copper and Zinc alloy 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.
