Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer specializing in high-quality industrial valves. With an annual export value of US$1 Million to US$1.5 Million, we have built a reputation for reliable products and excellent service. Our Factory Direct Marine Globe Check Valve made from Carbon Steel with Flanged Ends and Rising Stem design is engineered to meet the rigorous demands of marine and industrial applications. Combining the functions of a globe valve and a check valve, this product offers precise throttling and automatic backflow prevention in one unit. Manufactured under ISO9001 quality management system, each valve undergoes strict testing to ensure long-term performance and safety. We stand behind our products with a comprehensive warranty, giving you peace of mind in critical operations.
Key Features & Technical Specifications
- Dual Functionality: Combines globe valve throttling with check valve non-return action, eliminating the need for two separate valves.
- Carbon Steel Construction: Robust and durable, suitable for high-pressure and high-temperature environments. Resistant to corrosion in marine atmospheres when properly coated.
- Rising Stem Design: Visual indication of valve position (open/close) allows easy operation and maintenance. Stem threads are protected from media.
- Flanged Ends: Standard flanges (ANSI, DIN, JIS available upon request) ensure easy installation and leak-proof connection with piping systems.
- Reliable Sealing: Metal-to-metal or optional soft seat provides tight shut-off and low leakage rates.
- Fire-Safe Design: Optional fire-safe construction meets API 607 or equivalent standards (available upon request).
- Low Maintenance: Simple structure reduces spare parts inventory and servicing time.
- Warranty Coverage: Each valve comes with a standard warranty covering manufacturing defects; extended warranty options are negotiable.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a globe check valve and a regular check valve?
A: A globe check valve combines the throttling ability of a globe valve with the automatic backflow prevention of a check valve. It can regulate flow and prevent reversal in one device, whereas a regular check valve only prevents backflow. -
Q: Can this valve be used for seawater applications?
A: Yes, the carbon steel body with appropriate coating (e.g., epoxy or zinc-rich primer) is suitable for marine environments. For highly corrosive seawater, we recommend optional stainless steel or duplex materials – please inquire. -
Q: What pressure ratings are available for this valve?
A: Standard pressure ratings include PN10/16/25/40 and Class 150/300. Custom pressure ratings are available upon request depending on your system requirements. -
Q: Do you provide a certificate of material or test report?
A: Yes, we supply material certificates and hydrostatic test reports with each order. Additional third-party inspection (e.g., BV, Lloyds) is possible at extra cost. -
Q: Is the rising stem fully open indicator reliable?
A: The rising stem provides a clear visual indication of the valve position. Stem travel is limited by the bonnet, and the handwheel position shows open/close status accurately. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from date of shipment against manufacturing defects. Extended warranty up to 24 months is negotiable depending on the project. -
Q: Can the flanges be supplied with different drilling patterns?
A: Absolutely. We can machine flanges to match ANSI B16.5, DIN 2633, JIS B2220, GB/T 9119, or your specific drilling template. -
Q: How long is the typical lead time?
A: For standard sizes (DN50-DN300), lead time is approximately 15–25 working days. Larger sizes or special materials may require 30–45 days. Contact our sales team for current lead times.
Note: All technical parameters are based on standard configurations. Customizations and special requirements are welcome – please consult our engineers for your exact needs.
