Excavator one-way valve accessories
Many actions of the excavator are inseparable from the application of the check valve, and the problem of the check
valve will cause the abnormal operation of the excavator and the failure of the hydraulic system.
Check valves are divided into two types, ordinary check valves and hydraulic control check valves. The function of the ordinary check valve is to control the oil flow in one direction, and the reverse is cut off, so it is also called the check valve, which requires small resistance and loss in the forward flow, good reverse sealing performance, and can not reverse flow back.
The hydraulic control check valve is also known as the hydraulic lock and pressure valve, and the same as the check valve is to prevent the reverse flow of oil, the difference is that the hydraulic circuit needs the reverse flow of oil and can use the control oil pressure to open the check valve, in simple terms, the hydraulic control check valve can realize the flow of oil in two directions.
