ProVia Hand Brake Valve PRO6450040 Parking Spring Brake Control Valve for Heavy Duty Truck Pneumatic Brake System

The ProVia ProVia Hand Brake Valve (part number PRO6450040) is a replacement component for the air brake and air suspension systems of heavy-duty trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include Max Working Pressure 10 bar, temperature range -40°C ~ +80°C, Port Threads M16*1.5, M22*1.5.

Pulling the lever applies the parking brake and pushing it releases, so the driver can control the spring brake chambers with a single, positive action. Stable pressure output and a robust body keep the switching reliable through years of heavy-duty service, and the sealed construction resists dirt and moisture.

Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.
