Product Description:

‌The advantages and features of Rexroth hydraulic check valves include:

‌Pressure holding function‌: Rexroth hydraulic check valves can ensure long-term pressure holding of the system and solve the short-term pressure holding problem caused by leakage of the slide valve and pipeline. By using the closing ability of the check valve, the oil circuit can maintain stable pressure for a long time‌.

‌Hydraulic cylinder support‌: In vertical hydraulic cylinder applications, Rexroth hydraulic check valves can avoid the situation where the piston rod falls due to gravity, effectively prevent unnecessary movement of the internal components of the hydraulic cylinder, and ensure the safety of the system‌.

‌Hydraulic cylinder locking function‌: When the directional valve is in the neutral position, the two hydraulic control check valves will automatically close to ensure that the oil in the two chambers of the hydraulic cylinder is tightly sealed, preventing the piston from moving due to external force, and achieving complete locking of the hydraulic cylinder‌.

‌Fast response and high sensitivity‌: Rexroth SV20PB2-4X check valve, with its double-acting hydraulic control method, exhibits the characteristics of fast response, high sensitivity and large flow‌.

‌Precautions for using Rexroth hydraulic check valves include:

‌Ensure sufficient control pressure‌: Rexroth hydraulic check valves require stable control pressure, and any pressure fluctuations may cause malfunctions. Especially when the control pressure comes from the main system, pay close attention to the impact of changes in the main system pressure on the control oil circuit.

‌Choose a suitable structure and oil leakage method‌: According to the position of the Rexroth hydraulic check valve in the hydraulic system and the size of the flow resistance after the reverse oil outlet cavity, choose a suitable structure and oil leakage method. This ensures the normal operation of the valve and avoids failures caused by improper structure.

‌Prevent pressure loss‌: It is necessary to ensure that the Rexroth hydraulic check valve has sufficient control force, and pressure loss of the control force is not allowed. The control pressure should pay attention to whether it meets the reverse opening requirements.
