Aviation Fuel Supply System Oil Filter Housing RYL50-025W

a. Filtering Materials and Precision: There are three types of filtering materials available for this series of products: Type I is stainless steel special mesh, and the filtering accuracy is divided into 5, 8, 10, 16, 20, 25, 30, 40, 50, 80, 100 microns, etc. Class II is stainless steel fiber sintered felt, with a filtration accuracy of 5, 10, 20, 25, 40, 60 microns, ect; Class III is a glass fiber composite filter material, with a filtration accuracy of 1, 3, 5, 10 microns, ect.

b. When the temperature of the working medium and the fuel temperature of the filter material are ≥ 60 ℃, the filter material should be stainless steel special mesh or stainless steel fiber sintered felt, and the filter element should be fully welded with stainless steel; If the fuel temperature is ≥ 100 ℃, special instructions should be given during selection.

c. When the selection of pressure difference alarm and bypass valve filters requires the use of a pressure difference alarm, it is recommended to use a visual type pressure difference alarm with alarm pressures of 0.1MPa, 0.2MPa, and 0.35MPa. Visual alarm on site and remote telecommunication alarm are required. When there is a high demand for flow rate, it is recommended to install a bypass valve to ensure normal fuel supply in the fuel system when the filter is clogged and an alarm is triggered.

d. Selection of oil drain valves above RYL-50. It is recommended to consider adding an oil drain valve when selecting. The standard oil drain valve is a manual switch RSF-2. Below RYL-50, it is generally not installed. In special cases, it can be selected according to requirements: screw plugs or manual switches.
