SGF series double barrel high pressure filter

The filter is installed on the high pressure line of the oil outlet of the oil pump to protect the control element and the actuator. Especially in the automatic control system, high-precision servo components and plunger components can effectively prevent pollution and avoid failure, and extend the service life of components.

The filter is composed of two single barrel filters, reversing valve, bypass valve, transmitter, etc., which can make the system replace the filter element without stopping, and is suitable for continuous working hydraulic system.

When the filter element of one of the filters is blocked until the pressure difference transmitter pressure indicator value is 0.5MPa, the transmitter sends a signal, then the filter element must be replaced. As long as the reversing valve is turned, the other spare filter works immediately, then just unscrew the plug to discharge the oil, and then unscrew the housing, you can replace the blocked filter element. Need to replace the filter cartridge side to allow a small amount of internal leakage.

If the pressure difference of the filter element is not replaced in time for some reason, when the bypass valve opening pressure continues to rise to 0.6MPa, the bypass valve will automatically open to avoid re-pollution caused by the filter element rupture due to the pressure continuing to rise, but the user must replace the filter element when the transmitter sends a message.
