Fleet Products: 065206-G, 65206
OE: 108281, 1684489C91
Automann: 170.065206
DESCRIPTION:
Model: R-12 Relay Valve
Vehicles: Suitable for air brake-equipped heavy-duty trucks and trailers, including International applications
• Valve Type: Pneumatic relay valve for service brake application
• Function: Relays and accelerates the air signal from the brake pedal to rear brake chambers
• Actuation: Pneumatically triggered relay operation
• Mounting: Vertical orientation, 4-port delivery (2 vertical, 2 horizontal)
• Port Sizes:
– Supply: (2) 1/2"-14 NPT
– Delivery: (4) 3/8"-18 NPT
– Control: (1) 1/4"-18 NPT
– Exhaust: Includes dust shield
• Crack Pressure: 4.0 PSI (conflicting source also states 5.5 PSI; 4.0 PSI retained per your directive)
• Weight: 2.33 – 3.4 lbs (varies by source)
• Dimensions: Approx. 15.5 × 15 × 14 cm (shipping size)
• Operating Temperature: -40°F to +200°F (-40°C to +93°C)
• Mounting Details: 4 mounting slots, 0.96 in × 0.40 in
• Unique Features:
– DuraDrain relay piston (variant dependent)
– Dust-shielded exhaust for improved protection
– Suitable for dual axle delivery and quick-release applications
• System Fitment: Optimized for rear brake circuit of air brake systems; supports consistent actuation speed and pressure balance
Applications:
Designed for use in commercial vehicle air brake systems to deliver consistent pressure to brake chambers via a relay-controlled configuration. Ensures faster brake actuation and release in rear axle circuits. Typically mounted near rear brake chambers for best pneumatic response in dual-axle configurations or multi-chamber brake systems.

IMPORTANT INSTALLATION NOTES:
✔ Ensure vertical orientation of the valve with exhaust port facing downward
✔ Torque cover cap screws to 80–120 in-lbs during assembly
✔ Torque exhaust cover screws to 20–30 in-lbs
✔ Lightly lubricate relay piston, o-rings, guide post, and cover bore with silicone-based grease (Dow Corning 55-M or equivalent)
✔ Do not re-torque after initial assembly – use specified torque values only at assembly time
