Shanghai Zhibang Valve Manufacture Co., Ltd proudly presents our Marine High Temperature Globe Check Valve – a robust solution engineered for demanding marine and industrial applications. As a manufacturer established in 2016 with an annual export value of US$1 Million to US$1.5 Million, we have supplied reliable valves to markets across North America, South America, Europe, Asia, Africa, and Oceania. Our globe check valve features a carbon steel body and metal seal, designed to withstand temperatures up to 425℃ and pressures from PN1.6 to 6.4MPa. With sizes ranging from DN15 to DN150 and a flanged connection, this valve offers durability and precision flow control. Certified with CCS (China Classification Society) and manufactured under our ISO9001 quality management system, it ensures compliance and reliability in critical marine systems.
At Zhibang Valve, we combine advanced manufacturing techniques with rigorous quality checks to deliver valves that meet the highest standards. Our flanged globe check valve is specifically designed to prevent backflow while allowing high-temperature media to pass through efficiently. Whether used in shipbuilding, offshore platforms, power plants, or petrochemical facilities, this valve provides long service life and minimal maintenance. Let’s explore its key features and technical specifications in detail.
Key Features and Advantages
- High Temperature Resistance: Operating temperature up to 425℃ ensures stable performance in steam and hot oil systems.
- Metal-to-Metal Seal: Provides excellent sealing under high pressure and high temperature, reducing leakage risk.
- Carbon Steel Body: Offers superior strength, wear resistance, and long-term durability in harsh marine environments.
- Flanged Connection: Facilitates easy installation and maintenance, compatible with standard pipe flanges.
- Wide Size and Pressure Range: Available from DN15 to DN150 with pressure ratings PN1.6 to 6.4MPa, covering diverse system requirements.
- CCS Certified: Meets the stringent standards of China Classification Society, ensuring safety for marine applications.

The globe check valve operates on the principle of a spring-assisted or gravity-based disc that closes when flow reverses, preventing backflow effectively. Its streamlined flow path minimizes pressure drop, making it ideal for high-temperature steam lines, boiler systems, and marine engine cooling circuits. The metal seal ensures tight shut-off even at elevated temperatures where soft seals may degrade.

Frequently Asked Questions (FAQ)
-
What is the maximum working temperature for this valve?
Our globe check valve is designed for continuous service up to 425℃ (800℉). For higher temperatures, please consult our engineering team for possible material upgrades. -
Is the valve suitable for seawater applications?
The standard carbon steel body is not recommended for direct seawater contact without protective coating. We offer optional epoxy or zinc-rich coating for enhanced corrosion resistance. Please specify your application when ordering. -
What certifications does this valve hold?
It is CCS certified (China Classification Society) for marine use, and our factory is ISO9001:2015 certified. Additional third-party certifications like DNV, BV, or ABS can be arranged at extra cost. -
Can I get the valve in other pressure ratings?
Yes, we supply PN1.6, PN2.5, PN4.0, and PN6.4 as standard. Other pressure classes such as Class 150 or Class 300 are also available upon request. -
What is the difference between a globe check valve and a swing check valve?
A globe check valve uses a guided disc that moves perpendicular to the flow, offering better sealing and lower noise but slightly higher pressure drop. It is preferred for high-temperature and high-pressure applications where tight shut-off is needed. -
How is the valve tested before shipment?
Each valve undergoes hydrostatic shell test at 1.5 times rated pressure and seat leakage test at 1.1 times rated pressure according to API 598 or equivalent standard. A test certificate is provided with each order. -
What is the typical lead time?
For standard sizes (DN15-DN100), lead time is around 15-25 working days. Larger sizes or customized valves may require 30-45 working days. We also offer express production for urgent orders. -
Do you provide installation instructions?
Yes, each valve comes with an installation and maintenance manual. Our technical support team is also available to answer any questions during installation or operation.
