Valve,Stop(R.H)

The excavator shut-off valve assembly, also known as the excavator shut-off valve, is an important component of the excavator’s hydraulic system. Its main function is to control the flow of fluid by the movement of the valve disc, allowing for either complete opening or complete closing of fluid flow within the pipeline. The working principle of this valve involves the vertical movement of the valve disc along the centerline of the valve seat, relying on the threaded rotation of the valve stem to ensure that the sealing surface of the valve disc tightly adheres to the sealing surface of the valve seat, thus stopping the flow of the medium. This design provides the shut-off valve with excellent cut-off functionality, enabling effective control of fluid flow.

Additionally, the excavator shut-off valve assembly has a certain capacity for flow regulation, although its primary purpose is not for flow adjustment. In some cases, it can be used to regulate flow. However, shut-off valves are not suitable for long-term use in pressure and flow regulation, as this may cause erosion and corrosion of the sealing surfaces, thereby damaging the sealing performance.

In summary, the excavator shut-off valve assembly plays a crucial role in the hydraulic system of the excavator. It not only ensures the flow of fluid when needed but also completely blocks the flow when not required, thereby protecting the safety and stable operation of the system.‌
