Bendix Brakes 800034 PP-DC Parking Brake Control Valve Dashboard Mounted

The Bendix 800034 PP-DC (Push-Pull Double Check) parking brake control valve is a dashboard-mounted air brake control valve that provides in-cab control of truck or bus parking brakes. This manually operated valve features a push-pull button design that releases or applies the parking brakes with simple manual operation.

• Automatic safety feature: moves from applied position to exhaust position (applying parking brakes) if total system pressure drops below 20-30 PSI
• Tractor trip pressure: 35 ± 5 PSI ensures reliable emergency brake engagement
• All ports are 1/4-18 NPT threads for supply, delivery, and exhaust connections
• Mounting holes: Four 1/4-20 UNC-2B threaded holes for secure dashboard installation
• Operating temperature range: -40°F to 200°F (-40°C to 93°C) for reliable performance in extreme conditions
