Forge Piston Closed Loop Diverter Valve

An atmospheric dump/blow off valve suitable for all 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 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.

Owen Developments and Forge Motorsport cannot 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.

This valve is available in either an anodised black finish or in (silver) alloy, please let us know your preference when you order.
