Stainless Steel Filter Cartridge Valve Element - Sewage Treatment Y-Type Filter

The stainless steel filter cartridge valve element for sewage treatment Y-type filter is a widely used equipment in the sewage treatment field. Below is a detailed introduction:

1. Structure & Working Principle

The Y-type filter mainly consists of an inlet pipe, filter cartridge, outlet pipe and blowdown port. The filter screen is usually made of stainless steel double-layer woven mesh or punched plate, with a built-in stainless steel frame to enhance pressure resistance. Its working mechanism is as follows: after fluid enters from the inlet, impurities are intercepted by the filter screen and deposited at the bottom of the cartridge, while clean fluid flows out from the outlet. When the pressure difference between the inlet and outlet exceeds 0.05MPa due to filter clogging, cleaning is required via a detachable design or automatic blowdown valve.

2. Technical Parameters

Nominal Diameter: Generally DN15-DN800, suitable for pipeline systems of different pipe sizes.

Operating Temperature: Common range is -30℃-200℃; some models with special materials can withstand higher or lower temperatures.

Filtration Precision: Typically 10-300 meshes, selectable according to specific sewage treatment requirements.

Operating Pressure: Common ratings are 1.0MPa and 1.6MPa; some filters have a pressure range of 0.6-5.0MPa.

3. Material Selection

Main Body Material: Common options include stainless steel 304, 316 and 316L, featuring good corrosion resistance and strength for various sewage environments.

Filter Frame & Screen Material: Usually the same stainless steel as the main body (e.g., 304, 316, 316L) to ensure filtration efficiency and service life.

Sealing Material: Common types are oil-resistant asbestos, nitrile rubber and PTFE, selectable based on working medium and temperature conditions.

4. Features & Advantages

Advanced Structure: Rational Y-type design ensures low flow resistance, effectively reducing pressure loss during fluid passage.

Easy Cleaning: The filter cartridge is detachable—simply remove, clean and reinstall, resulting in low maintenance costs.

Durable: Made of stainless steel, it offers strong corrosion and wear resistance, enabling stable long-term operation in harsh sewage environments.

5. Application Fields

This filter plays a key role in treating domestic wastewater and industrial sewage. It can be used as pre-treatment equipment to reduce suspended particles in water from 500 microns to below 50 microns. It is also applicable to water reuse projects, helping treated water meet national discharge standards and realize water resource recycling.

6. Price Range

Prices vary by brand, specification and material. For example:

NAYUAN NY-YGL model Y-type filter: 8,888 RMB/unit.

Stainless steel Y-type filter cartridges on Taobao: 1-100 RMB/piece.
