Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and ISO9001 certified, is proud to offer the Cast Iron Flange Swing Check Valve 150LB Class designed specifically for water pipeline systems. As a professional manufacturer with annual export value of US$1 million to US$1.5 million, we ensure each valve meets rigorous quality standards to prevent backflow and protect your piping network. Our swing check valves are engineered for durability, low maintenance, and reliable performance in demanding water applications.
This valve features a full-bore design that minimizes pressure loss, while the cast iron body provides excellent corrosion resistance and long service life. The flanged connections comply with international standards, making installation and maintenance straightforward. With a 150LB pressure class rating, it is suitable for low to medium pressure water systems. Below are the key technical specifications:
| Body Material | Cast Iron (GG25) |
| Disc Material | Ductile Iron / Stainless Steel (optional) |
| Seat Material | EPDM / NBR / Viton (optional) |
| Pressure Rating | 150LB (Class 150) |
| Flange Standard | ANSI B16.1 / ISO 7005-2 |
| Size Range | DN50 – DN300 (2" – 12") |
| Temperature Range | -10°C to 120°C (depending on seat material) |
| Operation | Automatic (gravity swing disc) |
Key Features & Benefits:
- Robust Cast Iron Body: Ensures high strength and resistance to corrosion in water environments, extending service life.
- Swing Disc Design: Low pressure drop across the valve, reducing energy consumption in pumping systems.
- 150LB Pressure Class: Suitable for standard water pipeline applications, providing reliable backflow prevention under moderate pressures.
- ISO Standard Compliance: Manufactured according to ISO 9001 quality management system, ensuring consistent performance and interchangeability.
- Flanged Ends: Easy installation and maintenance, compatible with standard pipe flanges (ANSI/ISO).
- Customizable Seats: EPDM for water, NBR for oil, Viton for chemical resistance – available upon request.
- Full Bore Opening: Minimizes turbulence and allows for pigging or cleaning operations.
- Low Maintenance: Simple construction with few moving parts reduces downtime and repair costs.
Technical Advantages:
- Leakage Prevention: The disc is designed to seal tightly against the seat under reverse flow, meeting zero leakage standards.
- Durability: Cast iron body with internal coating (optional epoxy) provides additional protection against scaling and rust.
- Versatility: Suitable for water, sewage, and compatible fluids in municipal, industrial, and agricultural pipelines.
- Compact Design: Face-to-face dimensions comply with ISO 5752 short pattern, saving space.

Frequently Asked Questions (FAQ)
-
Q: What is the 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 low pressure drop and suitability for horizontal or vertical upward flow. A lift check valve uses a piston or ball that lifts vertically, requiring higher pressure to open. Swing check valves are ideal for water pipelines with moderate flow rates. -
Q: Can this valve be installed vertically?
A: Yes, the swing check valve can be installed in vertical pipelines with upward flow direction. However, for vertical downward flow, a spring-assisted check valve may be needed. Please consult our technical team for specific installation conditions. -
Q: What is the typical pressure rating for this valve?
A: The valve is rated for 150LB (Class 150), which corresponds to a maximum allowable working pressure of approximately 285 psi at 100°F (38°C) for cast iron. Refer to ANSI B16.1 for detailed pressure-temperature ratings. -
Q: Is the valve suitable for hot water or steam?
A: The standard EPDM seat is suitable for water up to 120°C. For higher temperatures or steam, a metal seat or special elastomer (e.g., Viton) is required. Please specify your application when ordering. -
Q: Do you offer custom sizes or special coatings?
A: Yes, we offer custom sizes from DN50 to DN300 and optional internal epoxy coating for enhanced corrosion resistance. Contact us for more details. -
Q: What certifications does your factory hold?
A: Our factory is ISO9001 certified. We can also provide test certificates and material certificates upon request. Additional certifications such as CE or API are available for specific orders (please inquire). -
Q: What is the lead time for this valve?
A: Typically 15-30 working days depending on quantity and specifications. For urgent orders, we can expedite production. -
Q: How do I choose the correct size for my pipeline?
A: The valve size should match the pipeline inner diameter. For optimal performance, select a valve size equal to or slightly larger than the pipe. Our technical team can help with sizing calculations if needed.
