Shanghai Zhibang Valve Manufacture Co., Ltd is proud to present our high-performance Steam System Marine Globe Check Valve in carbon steel, model DN100 PN1.6MPa with flanged rising stem design. As an ISO9001-certified manufacturer with over 8 years of experience and annual exports exceeding US$1 million, we deliver quality valves that meet rigorous marine and industrial standards. This valve is specifically engineered for steam systems aboard ships and offshore installations, offering reliable backflow prevention and long service life.
Our globe check valve combines the functions of a globe valve and a check valve, providing tight shut-off and automatic reverse flow prevention. The rising stem mechanism gives clear visual indication of valve position, while the flanged connections ensure easy installation and maintenance. Made from premium carbon steel, it withstands high temperatures and pressures typical of marine steam applications.

Frequently Asked Questions
-
Q: Can this valve be used for superheated steam?
A: Yes, the carbon steel construction can handle temperatures up to 425°C, making it suitable for superheated steam systems. For higher temperatures, please consult our team for modified materials. -
Q: Is the valve fully bidirectional?
A: The globe check valve is designed to allow flow in one direction and automatically close when flow reverses. It is not a full bidirectional valve; proper installation orientation is required. -
Q: Does it come with a certificate of marine approval?
A: Yes, the valve is designed to meet CCS standards and a CCS certificate can be provided upon request. Also, ISO9001 certification is standard. -
Q: What is the typical lead time?
A: For standard DN100 PN1.6MPa models, lead time is 15-20 working days. Custom sizes or special materials may require 25-35 working days. -
Q: Can I get the valve with a pneumatic or electric actuator?
A: The current design is handwheel-operated rising stem. However, we can supply actuator-ready versions or retrofit actuators. Please specify your requirement when ordering. -
Q: What flange standards are used?
A: Standard flanges are per EN 1092-1 (PN16). Alternative standards like ANSI 150 or JIS 10K are available as options. -
Q: How do I maintain the rising stem?
A: Regularly lubricate the stem threads and keep the packing gland properly tightened. For marine environments, use anti-corrosion grease. Detailed maintenance manual is provided. -
Q: Do you offer samples for testing?
A: Yes, sample orders are welcome. We can provide a sample valve with commercial invoice; shipping cost to be covered by buyer. Contact our sales team for details.
