Shanghai Zhibang Valve Manufacture Co., Ltd., a trusted manufacturer since 2016, proudly presents our 316L Stainless Steel Pressure Reducing Valve specifically designed for seawater systems. This valve ensures stable outlet pressure from 0 to 1.6 MPa, offering superior corrosion resistance in harsh marine environments. With an annual export value of US$1–1.5 million and ISO9001 certification, our product combines precision engineering with durable materials to meet the rigorous demands of global seawater applications.
Our pressure reducing valve is crafted from 316L stainless steel, which provides excellent resistance to chloride-induced corrosion, pitting, and crevice attack—common challenges in seawater systems. The valve features a balanced piston design for accurate pressure control, ensuring minimal pressure fluctuation even under varying flow conditions. Whether used in desalination plants, shipbuilding, offshore platforms, or coastal industrial facilities, this valve delivers reliable performance and long service life.
Key Features & Technical Specifications
- Material: 316L stainless steel body and internal components – maximum corrosion resistance.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum inlet pressure for this valve?
A: The standard maximum inlet pressure is 2.5 MPa, but higher pressure ratings are available upon request. Please specify your inlet conditions when ordering. -
Q: Can this valve be used for other fluids besides seawater?
A: Yes, it is suitable for many corrosive fluids, including brine, chemicals, and high-chloride water. However, please confirm compatibility with our technical team. -
Q: What connection types are available?
A: We offer flanged connections (ANSI 150LB, DIN PN16, JIS 10K) and threaded connections (NPT/BSP). Custom flanges can be manufactured for special requirements. -
Q: How do I adjust the outlet pressure?
A: The valve is equipped with an adjusting screw under the cap. Turn it clockwise to increase pressure and counterclockwise to decrease. A pressure gauge port is provided for monitoring. -
Q: Is the valve suitable for underwater or submerged installation?
A: While the 316L material resists corrosion, the valve is not designed for continuous submersion. For submerged applications, we recommend additional protective measures or a special submersible version. -
Q: What is the lead time for standard sizes?
A: For common sizes (DN15-DN100), the lead time is typically 15–25 working days. Custom sizes may require 30–40 days. Contact us for current stock availability. -
Q: Do you provide OEM or private labeling services?
A: Yes, we offer OEM manufacturing with your brand name and specifications. Minimum order quantities apply – please inquire for details. -
Q: How do I maintain the valve for long-term use?
A: Regularly inspect seals and clean the strainer (if installed). Lubricate moving parts every 6 months. For seawater systems, flush with fresh water after prolonged shutdown to prevent salt crystallization.
