Shanghai Zhibang Valve
Shanghai Zhibang Valve Manufacture Co., Ltd, a professional manufacturer established in 2016, proudly presents our API 6D Check Valve, ANSI Class 300, Carbon Steel Body, Swing Type for Crude Oil Pipeline. This valve is engineered to deliver reliable backflow prevention and long service life in demanding oil and gas applications. With ISO 9001 certification and an annual export value of US$1-1.5 million, we ensure that every valve meets stringent quality standards. Our swing check valve is designed for crude oil pipelines, offering minimal pressure drop and smooth operation, making it an ideal choice for upstream and midstream projects.
Key Features & Technical Specifications
- Robust Carbon Steel Body: Manufactured from A216 WCB carbon steel, providing excellent strength and durability in harsh environments. The body is designed to withstand high pressure and temperature fluctuations typical in crude oil pipelines.
- API 6D Compliance: Fully conforms to API 6D standard, ensuring reliable performance, tight sealing, and interchangeability. The valve is tested according to API 598 for shell and seat leakage.
- Swing Type Disc: The disc swings freely on a hinge, allowing for full flow when open and quick closure when reverse flow occurs. This design minimizes pressure loss and reduces water hammer effects.
- Flanged Ends: Standard raised face (RF) or ring-type joint (RTJ) flanges per ASME B16.5, compatible with ANSI Class 300 piping systems. Available in sizes from 2 inch to 24 inch (DN50 to DN600).
- Soft Seal or Metal Seal Options: Seat can be provided with PTFE or nylon insert for bubble-tight shut-off, or metal-to-metal seal for high-temperature applications. Both options are customizable based on specific service conditions.
- Blowout-Proof Stem: The stem is designed to prevent accidental ejection under pressure, enhancing operational safety.
- Lever and Weight or Counterweight: Optional accessories for controlled closing or to prevent slamming. Available upon request.

Frequently Asked Questions
-
Q: What is the main difference between a swing check valve and a lift check valve?
A: A swing check valve uses a disc that swings on a hinge, allowing full flow with minimal pressure drop. It is suitable for horizontal or vertical upward flow. A lift check valve uses a disc that lifts vertically, requiring a straight flow path and is often used in smaller sizes or higher velocities. -
Q: Can this valve be used for other media besides crude oil?
A: Yes, the carbon steel swing check valve is compatible with various liquid and gas media such as natural gas, water, and refined petroleum products, provided the temperature and pressure are within the specified limits. For corrosive media, alternative trim materials are available. -
Q: Is the valve supplied with a lever or weight for slam prevention?
A: By default, the standard valve is without accessories. However, we can provide lever and weight, counterweight, or dashpot options upon request to control closing speed and prevent slamming. -
Q: What certifications does the valve have?
A: Our manufacturing facility is ISO 9001 certified. The valves are designed and tested per API 6D and API 598. Additional third-party inspections (e.g., by SGS, BV) are available upon request at extra cost. -
Q: What is the typical lead time for a standard size valve?
A: For standard sizes (2-12 inch) in carbon steel, lead time is approximately 15-25 working days. For larger sizes or special materials, it may be 30-40 working days. Please confirm with our sales team. -
Q: Can the valve be installed in a vertical pipeline?
A: Swing check valves are typically installed in horizontal pipelines with the disc hinge pin horizontal. For vertical upward flow, a spring-assisted swing check valve may be recommended. Please consult our engineers for proper selection. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment against manufacturing defects. Extended warranty options are available upon negotiation. -
Q: How do you ensure the quality of the valve?
A: Every valve undergoes hydrostatic shell test, seat leakage test, and visual inspection as per API 598. Material certificates are provided. Our ISO 9001 system ensures traceability and consistent quality control.
