Shanghai Zhibang Valve Manufacture Co., Ltd., an ISO9001-certified manufacturer established in 2016 with an annual export value of US$1–1.5 million, proudly introduces our Rising Stem Marine Angle Globe Check Valve. Designed specifically for demanding marine and industrial applications, this valve combines the functions of a globe valve and a check valve in a compact, angle-body configuration. The rising stem provides clear visual indication of valve position, while the cast steel body ensures long-lasting durability under high pressure. Whether you are managing ballast systems, cooling water lines, or fuel oil transfer, this valve offers reliable flow control and backflow prevention in one robust unit.
Our Rising Stem Marine Angle Globe Check Valve is engineered with precision and built to meet international standards. The valve features a full-port design for minimal pressure drop, a rising stem with an indicator to verify open/closed status, and a check valve mechanism that automatically prevents reverse flow. The angle body (typically 90°) allows for convenient piping layouts, saving space and reducing fitting requirements. It is available in sizes from DN15 to DN100, with pressure ratings from PN1.6 to PN6.4 MPa, making it suitable for a wide range of medium-pressure systems.
Key Features & Benefits
- Dual Functionality: Combines globe valve throttling with check valve backflow prevention, eliminating the need for two separate valves and reducing installation costs.
- Rising Stem Design: The stem visibly rises as the valve opens, providing instant visual confirmation of valve position for safe operation.
- Cast Steel Body: High-strength cast steel (WCB or similar) offers excellent resistance to thermal and mechanical stress, ensuring a long service life in marine environments.
- Compact Angle Configuration: The 90° angle body minimizes space requirements and simplifies piping layouts, especially in tight engine rooms or skid-mounted systems.
- Flanged Connections: Standard flanged ends (available upon request) facilitate easy installation and maintenance. Custom connection types (e.g., threaded or welding ends) are also available.
- Pressure Range: Covers PN1.6 to PN6.4 MPa, suitable for both low and medium pressure applications commonly found on ships and offshore platforms.
- Versatile Media Compatibility: Designed for water, oil, and gas applications. Optional seat and seal materials can be selected for aggressive media.
- Reliable Sealing: Metal-to-metal or soft-seal options ensure tight shut-off and minimal leakage under rated conditions.

Frequently Asked Questions (FAQ)
- Q: What is the difference between a rising stem globe check valve and a conventional check valve? A: Our valve combines the throttling and shut-off function of a globe valve with the automatic backflow-prevention of a check valve. The rising stem allows you to visually confirm the disc position, making it ideal for systems where verification of operation is critical.
- Q: Can this valve be used for seawater service on ships? A: Yes, the cast steel body with appropriate corrosion-resistant coatings and optional stainless steel trim makes it suitable for seawater. Please specify the media when ordering so we can recommend the best material/coating combination.
- Q: What pressure ratings are available? A: The standard pressure ratings are PN1.6, PN2.5, PN4.0, and PN6.4 MPa. Other pressure classes (e.g., Class 150, 300) can be manufactured upon request with suitable design modifications.
- Q: Are these valves supplied with a manufacturer's test certificate? A: Yes, each valve comes with a standard inspection and test certificate in accordance with ISO9001. Additional third-party inspection (such as by Bureau Veritas or Lloyd’s) can be arranged at extra cost.
- Q: What is the typical lead time? A: For standard sizes and materials, lead time is approximately 20–30 days after order confirmation. Custom orders may require 30–45 days depending on complexity. Please contact our sales team for an accurate schedule.
- Q: Do you offer flanges to ANSI or DIN standards? A: Yes, we can provide flanges according to ANSI B16.5, DIN EN 1092-1, or GB/T 9113 as requested. Please specify the standard you require when placing an order.
- Q: How do I select the correct size and pressure rating for my system? A: Determine your maximum operating pressure and pipe diameter. We recommend using a valve rated at least 1.5 times the system’s working pressure. Our engineers can assist with selection based on your flow rate, temperature, and media.
- Q: What is the warranty period? A: We offer a 12-month warranty from the date of shipment against manufacturing defects. Extended warranties are available on request.
