OnSpot Pressure Protection Valve
The OnSpot Pressure Protection Valve is a key component used in the air supply system for Onspot automatic tire chains. The primary function of the PPV is to ensure that the vehicle’s air brake system maintains adequate air pressure even when the Onspot system is in use.
The Onspot system typically utilizes the vehicle’s existing compressed air supply, which is also used for the air brake system. Since air brakes are critical for the safe operation of the vehicle, it is essential to make sure that activating the Onspot chains does not compromise the air pressure needed for braking.
The Pressure Protection Valve works by allowing air to flow to the Onspot system only when the air pressure in the main air reservoir is above a certain threshold, typically around 70-80 psi (4.8-5.5 bar). If the air pressure drops below this level, the PPV automatically cuts off the air supply to the Onspot system, ensuring that the air brakes maintain their priority for available air pressure.
By installing a Pressure Protection Valve in the air supply line for the Onspot chains, operators can have confidence that their tire chain system will not interfere with the vehicle’s braking capabilities. This is particularly important for heavy vehicles like trucks and buses, where the proper functioning of the air brake system is crucial for safety.
Onspot Tire Chains is a company that specializes in manufacturing and supplying automatic tire chain systems, specifically designed for a range of commercial vehicles, including trucks, buses, and emergency vehicles. The company’s innovative traction solutions are aimed at improving safety and efficiency during harsh winter conditions.
