Shanghai Zhibang Valve Manufacture Co., Ltd, established in 2016, specializes in manufacturing high-quality industrial valves for marine, oil & gas, and industrial projects. With an annual export value of US$1 – US$1.5 million and ISO9001 certified quality management system, we are proud to introduce our DN100 PN1.6MPa Marine Carbon Steel Globe Check Valve – Flanged Connection, Rising Stem, CCS Approved. This valve combines the functions of a globe valve and a check valve in one compact body, offering reliable flow control and automatic backflow prevention for critical marine piping systems. Built from premium carbon steel, it is designed to withstand harsh marine environments and deliver long service life.
Our globe check valve is engineered to meet the strict requirements of marine classification societies. The CCS (China Classification Society) type approval ensures compliance with international maritime standards. The rising stem design provides a clear visual indication of the valve position, making operation and maintenance straightforward. Whether you need to regulate flow or protect your system from reverse flow, this valve offers a compact, cost-effective solution.

Advantages & Benefits for Customers
- Dual Functionality – Combines globe valve (flow regulation) and check valve (backflow prevention) in one unit, saving space and reducing piping complexity.
- Marine-Grade Durability – Carbon steel body with anti-corrosion coating, designed to resist seawater and aggressive media in shipboard systems.
- Reliable Sealing – Metal-to-metal seat or optional soft seat for bubble-tight shut-off, complying with CCS hydrostatic tests.
- Visual Position Indication – Rising stem clearly shows whether valve is open or closed, enhancing operator safety and control.
- Easy Maintenance – Bolted bonnet design allows quick internal inspection and replacement of seat/disk without removing valve from pipeline.
- Cost Savings – One valve performs two functions, reducing procurement cost, installation time, and maintenance inventory.
- Wide Application – Suitable for seawater cooling systems, ballast lines, fire-fighting systems, fuel oil transfer, and general marine piping.
- Customizable Options – Available with lockable handle, gear operator, electric/pneumatic actuator, and special coatings upon request.
The valve is manufactured under a strict ISO9001 quality system, and each unit is 100% pressure-tested before shipment. Our engineers can also provide assistance in selecting the correct trim materials (e.g., 13Cr, SS304, or Stellite) based on your specific media and temperature requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a regular globe valve and a globe check valve?
A: A globe check valve combines both functions: it can be manually operated like a globe valve to regulate flow, and it automatically closes when reverse flow occurs (acting as a check valve). It saves space and eliminates the need for a separate check valve. -
Q: Is CCS certification included with this valve?
A: Yes, the valve is designed and type-approved by CCS (China Classification Society) for marine applications. A CCS certificate can be provided upon request. -
Q: Can this valve be used for seawater service?
A: Yes, the carbon steel body with proper coating (e.g., epoxy or nylon) and suitable trim materials (e.g., bronze or stainless steel) can withstand seawater corrosion. We recommend consulting our engineers for the best material selection. -
Q: What flange standards are available?
A: The flanges conform to ASME B16.5 (Class 150) or EN 1092-1 (PN16). Custom flange drilling (e.g., JIS, DIN) is available upon request. -
Q: What is the maximum operating temperature?
A: Depending on the seat material, the temperature range is -20°C to +400°C. For high-temperature applications, we recommend a metal seat (stellite faced) design. -
Q: Do you offer an actuator for remote operation?
A: Yes, we can fit the valve with pneumatic, electric, or hydraulic actuators. Please provide your control requirements (e.g., on/off, modulating, 24V/220V). -
Q: How long is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment, covering manufacturing defects. Extended warranty is available upon negotiation. -
Q: What is the typical lead time for DN100 PN1.6MPa globe check valves?
A: For standard valves in stock, lead time is 7-15 days. Custom orders may require 30-45 days depending on quantity and special requirements.
