Product Features & Technical Specifications:
- High-Quality Material: Constructed from 316L stainless steel, providing excellent resistance to corrosion, pitting, and crevice corrosion, especially in chloride-containing environments. This ensures long service life and reduces maintenance costs.
- Wafer Type Design: The compact wafer style allows for installation between two flanges without additional bolting, saving space and weight compared to flanged check valves. This design simplifies installation and reduces overall system footprint.
- Full Port Configuration: Features a full port (full bore) design that minimizes flow restriction and pressure drop, allowing for maximum fluid throughput. This is crucial for applications requiring high flow efficiency and minimal turbulence.
- Pressure Rating: Rated for 150 LB WOG (Water, Oil, Gas), indicating its suitability for a wide range of media and pressure conditions up to 150 psi at room temperature, ensuring versatile application across industries.
- Standard Compliance: Manufactured according to the CB/T4303 standard, a Chinese technical standard for valves, ensuring dimensional consistency, performance reliability, and compatibility with related piping systems.
- Reliable Sealing: Depending on the specific model, sealing can be achieved via metal-to-metal contact or optional soft seats (like PTFE) for tighter shut-off and adaptability to different fluid types.
- Spring-Assisted Closure: Typically incorporates a spring mechanism to ensure prompt and positive closure upon flow reversal, preventing backflow and protecting upstream equipment.
- Quality Assurance: Each valve is accompanied by a Mill Test Report (MTR), providing traceability and verification of the material's chemical composition and mechanical properties, giving buyers confidence in material authenticity.

Frequently Asked Questions (FAQ):
-
Q: What does "150 LB WOG" mean for this valve?
A: "150 LB WOG" indicates the valve's pressure rating. It is suitable for applications with water, oil, or gas media at a pressure of 150 pounds per square inch (psi) at room temperature conditions. It defines the valve's working pressure limit for these common fluids. -
Q: How does a wafer type check valve differ from a flanged check valve?
A: A wafer type valve is designed to be installed between two pipeline flanges, using the flanges' bolts for connection. It is typically lighter, more compact, and requires less space than a flanged check valve, which has its own flanged ends for direct bolting to the pipeline flanges. -
Q: What are the advantages of using 316L stainless steel instead of 304?
A: 316L stainless steel contains molybdenum, which significantly enhances its corrosion resistance, particularly against chlorides, acids, and seawater. 316L also has a lower carbon content ("L" grade) for better weldability and resistance to sensitization. It is preferred for more aggressive corrosive environments compared to 304. -
Q: Is this valve suitable for high-temperature applications?
A: While 316L stainless steel can withstand elevated temperatures, the specific temperature rating for this valve model depends on factors like seat material and spring design. For precise high-temperature service limits, please consult with us for detailed specifications based on your application parameters. -
Q: What is included in the Mill Test Report (MTR)?
A: The Mill Test Report provides certified data from the material manufacturer. It typically includes the chemical composition analysis (percentages of elements like Cr, Ni, Mo, C), mechanical properties (tensile strength, yield strength, elongation), heat treatment information, and sometimes the original mill batch number, verifying the material meets specified standards. -
Q: Can this valve be used for steam service?
A: The "150 LB WOG" rating typically refers to water, oil, and gas. For steam service, specific ratings like "150 LB Steam" may apply, and design considerations differ. Please inquire about steam application suitability, as it may require validation against relevant standards and potential modifications. -
Q: What flange standards does this wafer valve fit between?
A: The valve is designed to fit between standard ANSI/ASME flanges (like ANSI B16.5) with common facing types such as Raised Face (RF) or Flat Face (FF). Specific flange dimensions (e.g., ANSI 150, 300) should be confirmed based on the valve size you require. -
Q: Are different seat materials available for this check valve?
A> Yes, seat materials can often be customized. Standard may be metal-to-metal, but soft seats like PTFE (for better sealing on clean fluids) or other materials may be available upon request to suit specific fluid compatibility or sealing requirements.
