Commercial vehicle brake pads convert the kinetic energy of the vehicle to thermal energy by friction. The ProVia brake pad portfolio covers the most commonly fitted air disc brakes in the market. Over 20 different pad kits, that also have optional accessories, ensure an optimal fit for all major applications.
Coupling heads enable the pneumatic connection between a truck and trailer. It connects two separate lines of supply and control, to prevent incorrect coupling.
Coiled tubes are applied to pneumatic braking systems to provide a flexible connection between the towing vehicle and semi-trailer.
Relay valves rapidly increase or decrease the pressure of compressed air and shorten the response and pressure build-up times in air braking systems. Relay valves not only help to rapidly pressurize the brake cylinders, but also act as quick-release valves when the brakes are released.
Inside the pneumatic system, the air dryer cartridge is an important, safety-relevant component. Installed between the compressor and reservoirs a cartridge is the first line of defense protecting a vehicle’s air system.
Pressure limiting valves help ensure system pressures are kept below a desired upper limit and maintain a set pressure in relevant parts of the circuit. Most pneumatic systems are designed to operate within a preset pressure range. Without controlling or limiting these forces, power components (and expensive equipment) could be damaged.
The valves prevent the buildup of excessive pressure or vacuum which can unbalance the system. They are the safeguards which limit maximum pressure in a system by releasing it when it gets too high.
The clutch servo enables the driver to disengage and engage the clutch with minimum clutch pedal effort. The clutch servo is a pneumatically assisted hydraulic clutch-actuating device that enables sensitive and accurate actuation of the clutch in the vehicle.
A ProVia Relay Emergency Valve (REV) controls a two-line trailer brake system actuated by the braking system of the tractor. The product controls the emergency brake function, triggering automatic trailer braking when a partial or total pressure drop is detected in the supply line. Available in variants compatible with a wide variety of OE systems, the ProVia REV is a cost-effective alternative to OE components.
A wheel speed sensor (WSS) is a device designed to read the speed of a vehicle's wheel rotation. The system also monitors the proper functioning of a range of features, including brake performance, ensuring vehicle safety.
ProVia wheel speed sensors are contactless and use alternating voltage outputs to correspond to the actual wheel speed rotation, passing the information to the vehicle’s electronics system.
A Rotary Slide Valve controls the raising and lowering of airsuspension based vehicles with a hand lever. ProVia offers a robust, cost attractive, high performance Rotary Slide valve.
Spring Brake Actuators consist of both a service and a parking chamber. The
air pressure applied into the service chamber is converted into mechanical
output force. The parking chamber provides the mechanical braking force to
park the vehicle. In addition, a mechanical release arrangement is provided in
the unit to release the parking brake after brake failure.
Air dryers are installed between the air compressor and the reservoir
on commercial trucks and busses. They are designed to filter out
humid air and other contaminants before they are able to reach the
vehicle’s downstream pneumatic systems.
A heater can be fitted to an air dryer as an option. ProVia recommends the use of a heater as part of the air dryer system, ensuring the system operates at a normal operating temperature and to protect it in low temperature environments.
A ProVia cabin levelling valve improves driver comfort by maintaining a precise cab position. For cabs fitted with an air suspension system, the CLV will preserve the correct attitude , intelligently adapting to cabin load and a wide range of road conditions.
Designed specifically for the aftermarket, ProVia is a budget brand with no frills – but also zero compromises on safety. The ProVia CLV is a robust component you can depend on.
The ProVia Air Processing Unit (APU) is a two-part system comprising a ProVia air dryer and a ProVia multi-circuit protection valve. It will dry and clean air supplied by the compressor, adjust pressure for the respective load circuits and provide overload protection.
The ProVia APU offers significantly better performance than budget brand competitors, and a longer operating life that greatly reduces maintenance downtime.
The Multiple Circuit Protection Valve (MCPV) from ProVia provides pressure protection in multi-circuit braking systems. Used in a trailer braking system, an MCPV distributes compressed air, adjusts pressure to the respective circuits and protects healthy circuits in cases of circuit failure.
ProVia’s MCPV offers significantly better performance than budget brand competitors and a longer
operating life that greatly reduces maintenance downtime.
ProVia offers competitive compressor repair solutions for commercial vehicles of all types, providing reliable performance at an attractive price.The range now includes a replacement cylinder head to control airflow through the compressor, compatible with a wide range of trucks and buses in the heavy, medium and light vehicle markets.
DDSB consists of service brake chamber and a spring brake chamber. The air pressure applied into the service chamber is converted into mechanical output force. The spring chamber provides the mechanical braking force to park the vehicle.
In addition, a mechanical release arrangement is provided in the unit to release the parking brake after brake failure. ProVia offers a cost attractive, high performance spring brake actuators for commercial vehicles.
A Chassis Levelling Valve from ProVia provides suspension control for vehicles
fitted with air springs. It precisely modulates compressed air in the suspension
bellows as a ratio of the vehicle’s load. The Chassis Levelling Valve ensures a
constant ride height, charging the air suspension during loading and venting when
unloading. It has been designed as a cost-effective alternative to OE components
with no compromise on safety. Available in a range of variants, it is designed for
compatibility with a wide choice of OE systems.
The ProVia Foot Brake Valve (FBV) is used for precise pressurisation and purge
of pneumatic dual-circuit braking systems, actively controlling the braking
process. It works in harness with actuating mechanisms across an extensive
range of commercial vehicles. ProVia’s FBV is a competitive price unit that
does not compromise safety. It is designed to secure both air circuits, allowing
the vehicle to be operated safely at all times.
