Shanghai Zhibang Valve Manufacture Co., Ltd has been a dedicated manufacturer of high-performance marine valves since 2016. Our Marine Bronze Pressure Reducing Valve is specifically engineered for seawater piping systems, offering reliable pressure regulation from DN15 to DN50 and PN1.0 to PN2.5MPa. With CCS certification and ISO9001 quality management, this valve ensures long service life and stable operation in harsh marine environments. Built from premium bronze, it resists corrosion and biofouling, making it an ideal choice for shipbuilding, offshore platforms, and coastal desalination plants.
Our valve is designed to meet the strictest marine standards, providing accurate downstream pressure control regardless of upstream fluctuations. The bronze body and internal components guarantee excellent resistance to seawater corrosion, while the advanced diaphragm and spring mechanism deliver smooth and precise pressure reduction. Each unit undergoes rigorous testing before shipment, ensuring zero leakage and reliable performance under extreme conditions.

The Marine Bronze Pressure Reducing Valve offers significant advantages over traditional cast iron or steel valves. Bronze is inherently resistant to seawater corrosion, reducing maintenance frequency and extending service life. The self-operated diaphragm design eliminates the need for external power or complex control systems, making installation and operation simple. Our valve also features a stainless steel spring and adjusting screw for precise pressure setting and long-term stability. Whether used in cooling water systems, fire-fighting lines, or ballast water treatment, this valve delivers consistent performance with minimal pressure drop.
For customers, the direct benefits include: reduced downtime due to fewer failures, lower spare parts inventory because of valve durability, and enhanced system safety through reliable pressure regulation. The CCS certification provides additional assurance that the valve meets international marine classification standards, facilitating vessel approval and inspection.

Frequently Asked Questions
-
Q: What is the maximum inlet pressure for this valve?
A: The maximum inlet pressure is 2.5 MPa (PN25). For higher pressures, please contact us for customized versions. -
Q: Can this valve be used in freshwater systems?
A: Yes, it works in both freshwater and seawater. However, the bronze material is particularly optimized for seawater corrosion resistance. -
Q: What certifications does this valve have?
A: The valve is CCS certified and our factory is ISO9001:2015 certified. Other marine classification certificates (like DNV, ABS) can be provided upon request and at additional cost. -
Q: What is the typical lead time?
A: For standard sizes (DN15-DN50) and pressure ratings, lead time is 15–25 working days. Custom orders may take 30–40 working days. -
Q: How do I adjust the outlet pressure?
A: The outlet pressure is adjustable by turning the adjusting screw on the top of the valve. A pressure gauge port is provided for monitoring. Detailed instructions are included with each valve. -
Q: Is the valve suitable for horizontal and vertical installation?
A: Yes, it can be installed in any orientation, though horizontal installation with the diaphragm upright is recommended for optimal performance. -
Q: What is the warranty period?
A: We offer a 24-month warranty from the date of shipment against manufacturing defects. This does not cover damage caused by improper installation, misuse, or normal wear. -
Q: Can I get a sample before bulk order?
A: Yes, sample orders are welcome. We can provide one unit for testing, with the sample cost deducted from the first bulk order if placed within 60 days.
