Flanged Marine Water Pressure Reducing Valve DN15-DN100 Cast Iron Body PN1.0-1.6MPa for Freshwater Systems
Product Spotlights
Shanghai Zhibang Valve Manufacture Co., Ltd, a trusted manufacturer established in 2016 with annual export value exceeding US$1 million, presents our high-quality Flanged Marine Water Pressure Reducing Valve in sizes DN15-DN100. Designed specifically for freshwater systems on ships and offshore platforms, this valve features a robust cast iron body and operates reliably at pressures from PN1.0 to PN1.6MPa. Its flanged connection ensures easy installation and leak-proof performance, making it an essential component for maintaining stable downstream pressure in marine environments.
Our pressure reducing valve is engineered to deliver precise pressure control, protect downstream equipment from damage, and reduce water hammer effects. The cast iron body provides excellent corrosion resistance and durability in saltwater-adjacent freshwater applications. With a compact design and reliable sealing, this valve minimizes maintenance needs and extends service life even under demanding conditions.

Frequently Asked Questions (FAQ)
-
What is the maximum inlet pressure for this valve?
The valve is designed for inlet pressures up to PN1.6MPa (16 bar). For higher pressures, please consult our engineering team for custom solutions. -
Can this valve be used for seawater or other corrosive fluids?
Standard model is for freshwater. For seawater or chemicals, we recommend optional bronze or stainless steel trimmed versions. -
What flange standards are available?
Standard flanges are per GB/T 17241 (PN10/PN16). DIN, ANSI, or JIS flanges are available upon request. -
Is the outlet pressure adjustable?
Yes, the valve has an adjustable spring that allows outlet pressure setting from 0.1 to 0.6 MPa (depending on inlet pressure). -
What maintenance is required?
Periodic inspection of the diaphragm and seals is recommended. Replace internal parts if leaking or pressure drift occurs. The cast iron body is durable with minimal maintenance. -
What is the typical lead time?
For standard sizes DN15-DN100, lead time is 15-25 working days. Quantity and customization may affect delivery. -
Do you provide certification for marine use?
Our valves are manufactured under ISO9001 quality system. Specific marine classification society certificates (e.g., CCS, DNV) can be arranged at extra cost. -
Can I get a sample before bulk order?
Yes, sample orders are welcome. We can provide a single unit for testing with freight collect.
