Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our DN15 to DN100 Marine Angle Globe Check Valve, manufactured from high-quality cast steel with pressure ratings from PN1.6 to PN6.4 MPa and flanged connections. As a dedicated manufacturer established in 2016 and certified under ISO9001, we combine precision engineering with marine-specific design to deliver a valve that effectively combines the functions of a globe valve and a check valve in one robust unit. This angle-style valve is engineered to withstand the demanding conditions of marine environments, offering reliable flow control and backflow prevention for a wide range of shipboard systems.
Our valve is designed to meet the rigorous standards of the maritime industry, ensuring long service life with minimal maintenance. The angle globe design reduces pressure drop and allows for compact installation in tight spaces, making it an ideal choice for ballast lines, cooling water circuits, and fire-fighting systems. Each valve is subjected to strict quality control procedures, and we offer customization options such as different seat materials (Stellite, stainless steel) and end flange types (RF, RTJ) to suit specific operational requirements.
Key Features & Technical Specifications
- Dual Functionality: Combines shut-off (globe valve) and check (non-return) functions in a single body, reducing the number of components in the pipeline.
- Angle Configuration (90°): Minimizes flow resistance and installation space compared to conventional straight-through designs.
- Cast Steel Construction: High mechanical strength and corrosion resistance, suitable for seawater, steam, and oil applications.
- Pressure Range: Covers PN1.6 through PN6.4 MPa (Class 150 to 300 equivalent), with optional higher ratings upon request.
- Flanged Ends: Standard raised face (RF) or ring joint (RTJ) flanges per ANSI B16.5 or DIN EN 1092-1, ensuring secure piping connections.
- Disc & Seat Trim: Standard stainless steel or Stellite hard-facing for extended wear life. Seat leakage meets API 598 Class VI.
- Design Standards: Conforms to BS 1868, API 602, and applicable marine classification society requirements (compliant upon request).

Operational Benefits for Marine Systems:
The angle globe check valve significantly reduces the number of pipe fittings and potential leak points. Its compact structure allows installation in confined engine rooms or pump stations. The guided disc ensures positive closing action, preventing reverse flow and protecting pumps and other equipment. With high-pressure capabilities up to PN6.4 MPa, this valve is suitable for critical applications such as main engine cooling circuits and high-pressure ballast systems.

Frequently Asked Questions (FAQ)
-
Q: Can this valve be used for steam service?
A: Yes, the cast steel body and stainless steel trim are suitable for saturated steam up to 425°C. For high-temperature steam, optional Stellite trim is recommended. -
Q: What is the difference between an angle globe check valve and a standard check valve?
A: An angle globe check valve combines the shut-off function of a globe valve with the backflow prevention of a check valve, reducing the need for two separate valves. The 90° angle also helps minimize space and pressure loss. -
Q: Are flanges included with the valve?
A: The valve is supplied with flanged ends (raised face or ring joint). Flange dimensions match ANSI or DIN standards. Custom flange drilling is available on request. -
Q: What pressure ratings are available?
A: Standard ratings are PN1.6, PN2.5, PN4.0, and PN6.4 MPa. For other pressure classes, please contact our sales team. -
Q: Does the valve require special maintenance?
A: Routine inspection is recommended to ensure seat and disc integrity. The valve is designed for low maintenance; however, periodic testing of the closing function is advised in critical systems. -
Q: Can I get a valve with a different material, like stainless steel or bronze?
A: Our standard material is cast steel (WCB). For corrosive media, we offer stainless steel or duplex options as customized products. Please inquire for non-standard materials. -
Q: Do you provide certificates for marine classification?
A: Yes, we can provide material certificates, hydrostatic test reports, and other documentation required by classification societies (ABS, DNV, Lloyd’s, etc.) upon request and at additional cost. -
Q: What is the lead time for a DN100 PN6.4 valve?
A: Typical lead time is 25–40 days, depending on quantity and customization. Rush orders can be expedited upon agreement.
