Proportioning Valve Description

Proportioning Valve, Knob Style.

The new generation of adjustable proportioning valves combines the latest refinements to deliver precise pressure metering and strength from a compact forged billet design. Pressure adjustments range from 100-1000 PSI and provide for a maximum decrease of 57% in line pressure, the most of any available valve. Adjuster knob with fine thread tuning provides precise pressure adjustment. This adjustment lets you fine tune the front to rear braking balance by proportionally decreasing the rear brake line pressure. Valves weigh only 5.2 ounces and have two .25” side mounting holes spaced 1.00” apart. This valve varies from our standard Knob Style Proportioning valve, as the in and out ports are 3/8-24 inverted flare seats and do not require tube nut adapters to directly install 3/8 tubing with inverted flare 3/8-24 nuts.

Combination Proportioning Valve

Wilwood’s new Combination Proportioning Valve substantially simplifies mounting, plumbing, wiring and brake proportioning adjustments on vehicles with custom brake systems. The combination block maintains full isolation between front and rear fluid circuits and can be used in conjunction with any tandem outlet or dual mount master cylinder assemblies. The rear circuit has a single inlet and single outlet with the adjustable proportioning valve. The front circuit has a single inlet with two outlets. It can be run as a single outlet with one outlet plugged, or used to split the plumbing on its way to the front calipers.

Proportioning Valve Description

Wilwood's GM style proportioning valve is a direct replacement for 1978 and newer General Motors vehicles equiped with front disc / rear drum brakes.Manufactured from high quality aluminum and coated with a durable black anodized finish. Line connections for the valve, if mounted in the OE location, Will allow the original lines to connect directly to the valve. If mounted in a non-OE location, fluid lines may have to be modified. This also does allow usage in other non-GM vehicles. This proportioning valve offers: 63% pressure reduction (rear) after 350 PSI knee point. A 30 PSI delay rear-to-front circuit and Circuit failure sender activation at 50 ± 10 PSI. A Recommended maximum operating pressure: 2000 PSI. Non-adjustable front-to-rear proportioning (knee point, rate, etc.) and Anti-dive or metering delay valve: Enables rear brake pressure to build momentarily before front brake pressure builds.

Proportioning Valve, Lever Style.

The new generation of adjustable proportioning valves combines the latest refinements to deliver precise pressure metering and strength from a compact forged billet design. Pressure adjustments range from 100-1000 PSI and provide for a maximum decrease of 57% in line pressure, the most of any available valve. This proportioning valve has six preset points actuated by moving a lever allowing racers to quickly adjust brake bias during a race. The lever “clicks” into the six positions for positive adjustment. Valves weigh only 6.1 ounces (lever), and have two .25” side mounting holes spaced 1.00” apart. Inlet / outlet ports are 1/8-27 NPT.

Residual Pressure Valve Description

Residual Pressure Valve 2lb, Blue, w/o Fittings.

Wilwood two pound residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in both disc and drum brake systems. The two pound valve is used in disc brake applications where the master cylinder is mounted below the horizontal plane of the calipers and fluid drain back occurs from gravity and vibration, thereby causing excessive caliper piston retraction and a longer brake pedal stroke. The minimal two pound residual pressure prevents fluid from flowing back without causing the brakes to drag. Residual Pressure Valves are made from billet aluminum and color coded for easy identification.

Residual Pressure Valve 10lb, Red, w/o Fittings.

Wilwood ten pound residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in drum brake systems. With drum brakes, a ten pound valve is used to compensate for return spring tension and maintain wheel cylinder sealing in the drums. Residual Pressure Valves are made from billet aluminum and color coded for easy identification.

Self Bleed Check Valve Description

Self Bleed Check Valve, Black.

Wilwood Check Valves, or Flow Control Valves are used in conjunction with our caliper Self Bleed Lines. Together they form a closed loop brake fluid system that allows small amounts of brake fluid to circulate every time the brake pedal is depressed, thereby eliminating the possibility of localized fluid boiling and build-up of gases within the brake fluid. Gases end up being vented back into the master cylinder reservoir rather than trapped within the caliper and brake lines. Our Check Valve accepts standard 1/8-27 NPT fittings. For plumbing instructions request Wilwood’s Data Sheet, DS-213.

Shutoff Valve Description

Brake Shutoff Valve & Solenoid, Electric.

This valve can be used as a brake shut-off. When energized, the valve will block pressure from reaching downstream. The valve does not prevent fluid from returning to the master cylinder. This eliminates the possibility of trapping pressure when activating the valve. Requires a 12 Volt, 5 amp (recommended) fused power source through a toggle switch. Warning: Not a line lock assembly. Not for street use. Please read instruction sheet available at http://www.wilwood.com/pdf/ds572.pdf before attempting installation
