PART NUMBER(S):

Fleet Products: 286500-G
OE: 286500, PR-4
Automann: 220222

DESCRIPTION:

Model: PR-4 Pressure Protection Valve
Vehicles: Compatible with heavy-duty trucks and trailers using air brake reservoir protection circuits
• Valve Type: Pressure-actuated, non-adjustable, normally closed
• Function: Protects primary reservoir from downstream failure; isolates accessory or secondary systems
• Supply Port: 1/4" NPT (female)
• Delivery Ports: 1/4" NPT (female, 3 outputs)
• Minimum Closing Pressure: 85 PSI (±5 PSI)
• Actuation: Opens at threshold pressure, automatically closes below setpoint
• Operating Temperature: -40°F to 200°F (-40°C to 93°C)
• Material: OEM-grade corrosion-resistant construction
• Mounting: Two 0.280" holes for universal bolt-on installation
• Weight: 0.68 lbs (0.31 kg)
• System Integrity: No delivery check valve; isolates failure zones while maintaining upstream pressure
Applications:
Used in truck and trailer air brake systems to prevent premature filling or drain of secondary reservoirs. Ensures the primary braking circuit remains operational by isolating accessory or auxiliary circuits that drop below system-safe pressure. Compatible with most OEM-spec air systems using PR-4 standard valves.
