Class 150 Flanged Y-Strainer

The Class 150 Flanged Y-Strainer is engineered specifically for Class 150 (PN20) pressure rating systems, with a body available in both carbon steel and stainless steel options to match different medium corrosion requirements. The 30° inclined filter chamber creates a smooth, streamlined flow path, reducing turbulence and pressure loss by up to 30% compared to conventional T-type strainers, while allowing heavier particles to naturally settle at the bottom of the screen chamber to extend maintenance intervals.

Flanged ends are machined to strict ASME B16.5 standards with raised face sealing surfaces, ensuring a tight, leak-proof seal with standard pipeline flanges. All bolt holes follow universal drilling dimensions for compatibility with global piping standards. All our Class 150 flanged Y strainers are fully CE certified in compliance with the EU Pressure Equipment Directive (PED 2014/68/EU). The certification covers the full size range from DN15 to DN300, including both carbon steel and stainless steel body materials, confirming that the product meets all safety requirements for EU pressure equipment.

Optimized Y-Type Design for Efficient Filtration

The Class 150 Flanged Y-Strainer adopts a compact Y-shaped chamber design that allows solid particles to settle naturally inside the filter body while maintaining smooth media flow. Compared with traditional filtration structures, its angled chamber layout helps reduce turbulence and unnecessary pressure loss, making it suitable for continuous pipeline operation. The stainless steel filter screen provides effective removal of rust, sediment, welding debris and other solid contaminants, helping protect pumps, valves, heat exchangers and other downstream equipment from damage.

ASME B16.5 Flanged Connection for Easy Pipeline Integration

Designed for industrial piping systems, the Class 150 Flanged Y-Strainer features flange connections manufactured according to ASME B16.5 standards, ensuring compatibility with common ANSI pipeline systems. The standardized flange design simplifies installation, replacement and maintenance for engineering projects. Whether used in new pipeline construction or existing system upgrades, the strainer can be easily integrated without complicated modifications.

Class 150 Pressure Rating for HVAC and Industrial Applications

The Y-Strainer is designed for pipeline systems operating under Class 150 pressure conditions, making it a practical choice for commercial HVAC systems, water circulation networks and general industrial applications.

In HVAC chilled water and cooling water systems, it is commonly installed before chillers, pumps, cooling towers and heat exchangers to remove impurities from circulating water. By maintaining cleaner fluid conditions, it helps improve heat exchange efficiency and reduces unnecessary equipment maintenance.

Protecting Critical Equipment from Pipeline Contamination

During long-term pipeline operation, impurities such as rust particles, scale and installation debris may enter the system and affect equipment performance.

The Class 150 Flanged Y-Strainer works as a protective barrier before sensitive components, reducing the risk of pump wear, valve blockage and heat exchanger fouling. This helps improve system stability and extend the service life of connected equipment.

Compact Structure with Convenient Maintenance Design

Space availability is an important consideration in many commercial and industrial installations. The compact structure of the Class 150 Flanged Y-Strainer allows flexible installation in equipment rooms and pipeline areas where space is limited.

The removable filter screen design makes routine cleaning and inspection easier. Operators can remove accumulated particles and restore filtration performance without replacing the complete unit, reducing maintenance time and operating costs.

Carbon Steel and Stainless Steel Options for Different Working Conditions

To meet different application requirements, we provide the Class 150 Flanged Y-Strainer with carbon steel and stainless steel body options.

Carbon steel models are widely used in general water, HVAC and industrial pipeline systems where strength and cost efficiency are important. Stainless steel versions are suitable for applications requiring better corrosion resistance and longer service life.

Different screen mesh sizes, connection standards and material configurations can be customized according to project requirements.

Cost-Effective Filtration Solution for Commercial and Industrial Projects

The Y-Strainer combines standardized design, easy maintenance and reliable filtration performance, making it suitable for both new construction projects and pipeline renovation applications.

From commercial building HVAC systems to industrial utility pipelines, it provides a practical filtration solution that helps reduce equipment downtime, simplify maintenance work and improve overall system reliability.
