Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our High Pressure Marine Globe Check Valve, featuring a forged steel body, PN16 rating, DN100 size, flanged connections, and a rising stem. Designed for demanding marine and high-pressure applications, this valve combines robust construction with precise engineering to ensure reliable flow control and backflow prevention. As an ISO9001-certified manufacturer since 2016, we deliver products that adhere to strict quality standards, serving markets across North America, Europe, Asia, and beyond.
Key Features & Technical Specifications
- Forged Steel Body – Provides exceptional strength and durability under high pressure and corrosive marine environments.
- Globe Check Valve Design – Combines the functions of a globe valve (throttling) and a check valve (automatic backflow prevention) in one unit.
- PN16 Pressure Rating – Suitable for nominal pressures up to 16 bar (approx. 232 psi) at moderate temperatures.
- DN100 (4-inch) Nominal Diameter – Ideal for medium-flow systems in marine pipelines.
- Flanged Ends – Standard raised-face or flat-face flanges for easy installation and leak-proof sealing.
- Rising Stem – Visual indication of valve position; stem rises when valve opens, enabling clear status monitoring.
- Standard Compliant – Designed and manufactured in accordance with relevant international standards (e.g., API, DIN, BS) to ensure interchangeability and performance.

Detailed Product Advantages
- Dual Functionality: Acts as both a globe valve for flow regulation and a check valve to prevent backflow, reducing the need for separate components.
- Marine-Grade Durability: Forged steel body resists corrosion from seawater and high-pressure environments typical in shipboard systems.
- Easy Maintenance: Rising stem design allows quick visual inspection of the valve position and simplifies maintenance checks.
- Leak-Tight Sealing: Flanged connections with gaskets ensure minimal leakage under pressure, enhancing system safety.
- Customizable Options: Available with different flange facings (RF, FF), trim materials, and coatings upon request.
- Standard Compliance: Manufactured to comply with relevant international standards (e.g., API 602, BS 1873, DIN 3840) to ensure compatibility with existing piping systems.

Frequently Asked Questions (FAQ)
1. What is the difference between a globe check valve and a regular check valve?
A globe check valve combines the throttling capability of a globe valve with the automatic backflow prevention of a check valve. It can be manually operated to regulate flow, and automatically closes when flow reverses, offering more control in a single valve body.
2. What materials are used for the seat and disc?
The standard configuration features 13% chrome stainless steel (SS420) for the seat and disc, providing good wear and corrosion resistance. Other trim materials (e.g., SS304, SS316, stellite) are available on request.
3. Can this valve be used for steam service?
Yes, the forged steel body and suitable trim materials allow operation with saturated steam up to 200°C (depending on pressure). However, please verify the exact temperature and pressure conditions with our engineering team.
4. What are the flange drilling standards for this PN16 valve?
Our PN16 flanges are typically drilled to EN 1092-1 or ISO 7005-2 standards. Other standards (e.g., ASME B16.5 Class 150) can be accommodated with custom machining.
5. Is the valve supplied with a handwheel? What type?
Yes, the rising stem design is operated by a handwheel. The standard handwheel is made of cast iron or steel, with an option for a locking device.
6. Do you provide a test certificate?
Yes, we provide a material certificate (EN 10204 3.1) and a hydrostatic test certificate upon request. Additional inspection by third-party agencies can be arranged.
7. What is the lead time for this valve?
Typical lead time is 2–4 weeks for standard configurations. Larger quantities or special materials may require additional time. Please contact us for current lead times.
8. Can I get a sample order before bulk purchase?
Yes, sample orders are welcome. We can ship a single unit for evaluation, and the sample cost can be deducted from the first bulk order.
