I. Basic Overview
The Y-type filter is an indispensable filtering device in the pipeline system for conveying media, also known as a dirt separator or filter valve. It is usually installed at the inlet end of pressure reducing valves, pressure relief valves, constant water level valves, or other equipment. Its main function is to filter mechanical impurities in the medium (such as rust, sand particles in sewage, and a small amount of solid particles in liquids), so as to protect the valves and accessories on the equipment pipeline from wear and blockage, and ensure the normal operation of the equipment.

II. Structural Composition
The Y-type filter is mainly composed of a connecting pipe, a main pipe, a filter screen, a flange, a flange cover, and fasteners.

III. Working Principle
When the liquid enters the filter basket through the main pipe, solid impurity particles will be blocked in the filter basket, while the clean fluid passes through the filter basket and is discharged from the outlet of the filter, thus realizing the filtration and purification of the medium.

IV. Design Features
– The filter screen adopts a cylindrical filter basket shape to increase its strength, making it stronger than a single-layer screen.
– The flange cover at the lower end of the Y-shaped interface can be unscrewed, which is convenient for regularly removing the particle impurities deposited in the filter basket.

V. Use and Maintenance
When cleaning is needed, you only need to take out the detachable filter cartridge, re-install it after treatment, so the use and maintenance are extremely convenient.

VI. Product Advantages and Application Scope
– Advantages: It has the characteristics of advanced structure, small resistance, and convenient sewage discharge.
– Applicable media: It can be corrosive media such as water, oil, and gas.
