As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance DN50-DN200 Flanged Suction Stop Check Box Valve. Engineered for reliability in demanding industrial applications, this valve is specifically designed to prevent backflow and protect critical equipment like pumps. With a robust cast iron body and a pressure rating of PN1.0MPa, it offers a durable and cost-effective solution for fluid control systems worldwide. Our commitment to quality, backed by an annual export value of US$1-1.5 million, ensures you receive a product that meets rigorous international standards for performance and longevity.
This valve combines the functions of a check valve and a stop valve in a compact, flanged design, making installation and maintenance straightforward. Its primary role is to allow fluid flow in one direction while automatically preventing reverse flow (check function) and providing a positive shut-off when required (stop function). This dual functionality is crucial for systems where pump protection and system isolation are necessary.
Key Features & Technical Advantages:
- Robust Construction: The valve body is manufactured from high-grade cast iron, known for its excellent strength, durability, and corrosion resistance, ensuring a long service life even in tough environments.
- Precise Flanged Design: Flanged ends (DN50-DN200) provide a secure, leak-proof connection to piping systems, simplifying installation and allowing for easy removal for inspection or service without disturbing the entire pipeline.
- Reliable Non-Return Mechanism: The internal check mechanism responds quickly to flow changes, closing automatically to prevent backflow, water hammer, and potential damage to upstream equipment like pumps.
- Integrated Stop Function: Unlike a standard check valve, this model includes a positive shut-off feature, allowing operators to isolate a section of the line completely when needed for maintenance or system adjustments.
- Optimized for Suction Service: Specifically engineered for pump suction lines, it helps maintain prime and prevent pump run-dry conditions, enhancing overall system efficiency and pump lifespan.
- Wide Pressure Compatibility: With a pressure rating of PN1.0MPa (approx. 10 bar), it is suitable for a broad range of low to medium-pressure applications in water supply, irrigation, industrial cooling, and general service lines.

Frequently Asked Questions (FAQ):
-
Q: What is the main difference between this valve and a standard check valve?
A: This valve incorporates both a check (non-return) function and a positive stop (shut-off) function. A standard check valve only prevents backflow automatically but cannot be manually closed to isolate flow. -
Q: Can this valve be installed in any orientation?
A: For optimal performance and to ensure the internal mechanism functions correctly, it is recommended to install the valve with the stem in a horizontal or upward position. Specific installation guidelines are provided with the product. -
Q: Is the cast iron body suitable for potable water applications?
A: The standard cast iron body is typically used for industrial water, irrigation, or general service. For potable water, specific internal coatings or material certifications may be required, which can be discussed as a custom option. -
Q: What fluids is this valve compatible with?
A: It is designed for water, air, and other neutral fluids compatible with cast iron and standard sealing materials at temperatures up to approximately 120°C. Compatibility with specific chemicals or oils should be verified beforehand. -
Q: Are the flanges drilled to standard patterns?
A: Yes, the flanges are manufactured to common industrial dimensional standards (like ANSI B16.1 Class 125 or equivalent) to ensure compatibility with standard piping flanges. Exact specifications are available upon request. -
Q: What is the lead time for orders?
A: Lead times vary based on order quantity and specific size requirements. Standard sizes (DN50-DN150) often have shorter lead times. Please inquire with our sales team for an accurate delivery schedule. -
Q: Do you offer different seat/disc materials?
A: Yes. While standard configuration includes durable materials like rubber and bronze, alternative materials such as EPDM, Nitrile, or stainless steel for specific wear or chemical resistance are available upon request. -
Q: How do I determine the correct size (DN) for my pipeline?
A: The valve size (DN) should match the nominal diameter of your connecting pipeline. Our technical team can assist you in selection based on your flow rate and pressure drop requirements.
