This non-return valve, also known as a check valve, is crucial for controlling the direction of hydraulic fluid flow within the system, preventing backflow. It is built to strict OEM standards, ensuring consistent sealing and reliable operation, unlike a worn valve that may leak or stick. Operators might notice a loss of hydraulic pressure, sluggish response, or unintended movement of actuators.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A malfunctioning non-return valve may initially cause a slight delay in hydraulic response or a minor loss of holding pressure. If the valve fails to seal properly, it can lead to a continuous loss of system pressure, resulting in slower operation and reduced lifting capacity. This can significantly hinder the excavator's ability to perform its intended tasks efficiently.
Ensure the valve is installed in the correct flow direction, as indicated by any markings on the valve body. Do not force the valve into place; if it does not seat easily, re-check the orientation and the port cleanliness.
Inspect associated hydraulic lines and fittings for leaks or damage when replacing a non-return valve.
