Hydraulic filter element bypass valve working principle

A. The definition of hydraulic filter by-pass valve

Hydraulic filter by-pass valve is a valve used for filter by-pass in hydraulic system. Common filter by-pass ways include check valve, throttle valve and bidirectional by-pass valve.

B. The working principle of the hydraulic filter by-pass valve

When the filter element of the hydraulic system is blocked, the flow rate of the oil inlet of the hydraulic system will be reduced, which will affect the normal operation of the system. To avoid this, a bypass valve is usually set up next to the filter element, so that when the filter element is blocked, the liquid can bypass the filter element and continue to flow.

The working principle of the hydraulic filter by-pass valve is to open or close the valve by using liquid pressure. When the filter element is working normally, the liquid passes through the filter element and smoothly enters the hydraulic system. At this time, the filter element bypass valve is closed. When the filter element is blocked, the pressure difference will cause the bypass valve to open, and the liquid can flow through the valve without being affected by the filter element into the hydraulic system to ensure the normal operation of the hydraulic system.

C. The advantages of hydraulic filter by-pass valve

1. Filter by-pass valve can extend the filter replacement cycle, reduce the maintenance frequency and maintenance costs;

2. Bypass valve normally closed state, does not affect the normal operation of the hydraulic system;

3. The bypass valve is used with the filter element to better protect the smoothness and stability of the hydraulic system;

4. The bypass valve can also set the corresponding control mode according to the special requirements of the hydraulic system, which is suitable for different working environments.

The hydraulic filter by-pass valve is an indispensable part of the hydraulic system, which can protect the filter of the hydraulic system and ensure the long-term stable operation of the hydraulic system.
