Founded in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd has established itself as a reliable manufacturer of high-performance industrial valves. With an annual export value of US$1 million to US$1.5 million, we serve clients across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and beyond. Our BV & RINA Certified Marine Angle Globe Check Valve in cast steel is a prime example of our commitment to quality and maritime engineering excellence. Designed for demanding marine and offshore environments, this valve delivers reliable backflow prevention with a compact angle design. With sizes ranging from DN15 to DN100 and a full 1-year warranty, it offers a trusted solution for shipbuilders, offshore platform operators, and industrial fluid systems.
Our factory adheres to ISO9001 quality management standards, ensuring every valve undergoes rigorous production and testing procedures. The angle globe check valve is specifically engineered to withstand high-pressure water, oil, and gas applications commonly found in marine piping systems. Its cast steel body provides exceptional strength and corrosion resistance, while the internal seat and disc design minimize flow resistance and ensure tight shut-off. Below we detail the key features and technical specifications.
Key Features & Benefits
- BV & RINA Type Approval: Certified by leading marine classification societies, guaranteeing compliance with international maritime standards for safety and reliability.
- Angle Body Design: Enables 90° flow direction change, saving space in tight piping layouts and reducing the number of fittings required.
- Cast Steel Construction: Robust and durable; suitable for high-temperature and high-pressure marine environments (up to 2.5 MPa / 25 bar, depending on size).
- DN15 to DN100 Range: Covers a wide spectrum of pipe diameters, offering flexibility for various marine systems including ballast, cooling, fire-fighting, and fuel oil lines.
- Automatic Check Action: Prevents reverse flow without manual intervention, protecting pumps, compressors, and other downstream equipment.
- 1-Year Warranty: Covers manufacturing defects; backed by our responsive after-sales support team based in Shanghai.
- Customizable Coatings: Standard blue paint is applied, but anti-corrosion coatings and special colors are available upon request.

In addition to the standard specifications, we offer optional trims such as stainless steel or stellite seat overlays for enhanced wear resistance. Our engineering team can also customize the valve for specific pressure classes or special media (e.g., seawater, steam). The angle globe check valve is particularly valued in marine engine rooms and cargo handling areas where space is at a premium. Its streamlined flow path reduces turbulence, improving system efficiency and reducing maintenance intervals.
At Shanghai Zhibang Valve, we understand the critical nature of marine operations. That is why every valve we ship undergoes pressure testing, seat leakage testing, and visual inspection in accordance with ISO9001 procedures. Our port of shipment options include Shanghai, Guangzhou, Hong Kong, and Beijing, ensuring efficient logistics to global destinations. With a growing export record of US$1 million to US$1.5 million annually and a broad market reach across 6 continents, we have earned the trust of shipyards, offshore contractors, and industrial distributors worldwide.
Why choose Shanghai Zhibang Valve? We combine competitive pricing, certified quality, and responsive customer service. Our lead times are typically 15-30 days, and we offer free sample evaluation for qualified projects. The BV and RINA certification gives you peace of mind that our marine angle globe check valve meets the most stringent classification society requirements.

Frequently Asked Questions (FAQ)
-
Q1: What does “angle globe check valve” mean?
A: It combines the functions of a globe valve and a check valve in an angled body (inlet and outlet perpendicular). It allows flow in one direction while automatically preventing reverse flow, and the 90-degree turn helps save space. -
Q2: Is the valve suitable for seawater applications?
A: Yes, but for seawater we recommend additional anti-corrosion coatings or using a duplex stainless steel trim. The standard cast steel is more suited for fresh water, oil, and non-corrosive media. Please consult our sales team for specific media compatibility. -
Q3: What certifications are included in the standard product?
A: Our standard product comes with ISO9001, BV (Bureau Veritas), and RINA type approval certificates. Copies can be provided upon request. Other classification society approvals (e.g., DNV, Lloyd’s) are available as optional extras. -
Q4: Can I get a sample before bulk order?
A: Absolutely. We provide free samples for qualified buyers; you only need to cover shipping costs. Sample lead time is about 7-10 days after confirmation. -
Q5: What is the lead time for a DN100 valve?
A: For standard sizes (DN15-DN100), our typical production time is 15-20 working days from receipt of deposit. Larger quantities may require 25-30 days. -
Q6: What pressure ratings are available?
A: Standard pressure ratings are PN16 and PN25 (equivalent to Class 150). Higher pressure classes (e.g., PN40, Class 300) can be manufactured upon request with corresponding design adjustments. -
Q7: Do you offer custom end connections?
A: Yes, we can produce flanges according to DIN, ANSI, JIS, or other standards. Threaded or welding ends are also possible for certain sizes. Please specify your requirements. -
Q8: What is your warranty policy?
A: We offer a 1-year warranty against manufacturing defects from the date of shipment. During this period, we will replace or repair any faulty valve free of charge (excluding misuse or improper installation).
