SINOTRUK HOWO Truck Parts Four-circuit Protection Valve WG9000360523
Basic information
Under normal circumstances, the four-circuit protection valve is actually a five-way joint, which only protects when a circuit breaks or leaks. The whole vehicle air circuit is divided into four circuits that are both interconnected and independent of each other. When any one circuit fails, it will not affect the normal operation and inflation of other circuits.
Our products have undergone strict technical tests, and there will be no quality problems of the products themselves.
Our company has always been adhering to the tenet of 'We don't develop business, we build relationships through better service'

Relevant knowledge
Working principle of four-circuit protection valve
Divide the dried gas into 4 circuits to meet the needs of different systems of the vehicle: service brake system, parking brake system, air suspension system, door control system, etc., while ensuring that other circuits can work normally when one circuit fails , and can properly supplement the air pressure of the failed circuit.
The four-circuit protection valve (hereinafter referred to as the four-protection valve) is composed of four pressure-limiting check valves arranged in a certain relationship, and some other functional mechanisms are appropriately attached to realize the branch supply of the air source in the commercial vehicle braking system to ensure that each The circuit works independently and normally. In general, each outlet of the four-circuit protection valve is opened first, first to ensure that the whole vehicle has the initial driving braking capability to ensure driving safety, and the other ports are opened randomly.
