Check Valve
- Swing Check Mechanism: Automatically opens with forward flow and closes instantly when reverse flow occurs, ensuring reliable backflow protection.
- Forged Brass Construction: High-strength brass body provides excellent corrosion resistance, mechanical durability, and long service life in demanding environments.
- Compact Threaded Design: Female threaded connections enable quick installation and compatibility with BSP or NPT piping systems.
- Low Maintenance Performance: Simple internal structure minimizes wear while delivering stable operation and dependable sealing over extended service periods.
It is designed to automatically prevent reverse flow in piping systems by allowing fluid to flow in one direction only. The internal swing disc opens under forward pressure and closes immediately when flow stops or reverses, ensuring reliable backflow prevention.

Technical & Sourcing FAQ
-
What is the function of the suction strainer screen?
The suction strainer screen is designed to capture sand, rust, scale, and other solid particles before they enter the suction line. By preventing contaminants from reaching pumps and downstream equipment, it helps reduce wear, improve system efficiency, and extend the service life of critical components. It is an essential replacement part for maintaining reliable filtration performance.
-
What materials are available for the filter screen?
The screen is manufactured from high-quality stainless steel mesh for excellent corrosion resistance and long-term durability, while the threaded base is made of brass for secure installation. SS304 is supplied as the standard material, with SS316 available upon request for applications involving more corrosive environments or higher performance requirements.
-
Is the strainer screen reusable?
Yes. The stainless steel mesh is designed for repeated cleaning and reuse under normal operating conditions. Regular maintenance helps maintain filtration efficiency, minimize pressure loss, and reduce replacement frequency, making it a cost-effective solution for long-term operation.
-
Can customized specifications be provided?
Yes. OEM and ODM services are available to meet different market and project requirements. Custom options include thread standards (BSPT/NPT), mesh size, screen material, dimensions, surface finish, and private labeling. Our engineering team can also support product customization based on customer specifications and application needs.
