The Y-type filter is a critical device in the medium conveying pipeline system for filtering impurities, commonly installed at the inlet end of pressure-reducing valves, pressure-relief valves, and other equipment to ensure their normal operation. Its core function is to intercept solid particles in the fluid through a filter mesh, thus preventing impurities from causing wear or blockage in subsequent equipment.

Structure and Working Principle

The Y-type filter consists of components such as the connecting pipe, main pipe, and filter basket. After the fluid enters the filter basket, impurities are trapped within the filter mesh, while the clean fluid passes through the basket and is discharged. It features a compact structure, low resistance, and easy waste removal, making it suitable for various media including water, oil, and gas.

Applicable Scenarios

‌Industrial Applications: Widely used in pipeline systems for chemical, power, environmental protection, and other fields, extending the lifespan of equipment such as compressors and pumps.‌

‌Installation Location: Typically set at the inlet end of devices such as减压阀 (pressure reducing valves) and泄压阀 (pressure relief valves) to ensure medium cleanliness.‌

Maintain and service

‌Cleaning Method: Regularly disassemble and clean the filter basket to remove impurities, and replace deformed or damaged filter screens.‌

Installation Precautions: Keep the pipe threads clean and ensure the direction of the inlet and outlet aligns with the arrow markings on the valve body.

Performance Parameters

‌Filter Mesh Precision: Water - 18-30 mesh/cm², Air - 40-100 mesh/cm², Oil - 100-480 mesh/cm².‌

Material Options: The housing is available in A3 carbon steel or 304 stainless steel, with sealing materials including polytetrafluoroethylene, etc.
