YONGCHENG KA-15 One-way Valve


One-way valves are used in situations where the reverse flow of air is not allowed. For example, when the air compressor is inflating the air tank, a one-way valve is set between the air compressor and the air tank. When the air compressor stops working, it can prevent the compressed air in the tank returning to the air compressor. One-way valves are also often combined with throttle valves and sequence valves to form one-way throttle valves and one-way sequence valves.
