Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Grade Pressure Reducing Valve with a 316L stainless steel body and spring, designed specifically for demanding marine environments. Rated PN16 with a maximum inlet pressure of 10 Bar, this valve delivers precise pressure regulation while resisting corrosion from saltwater and harsh chemicals. As an ISO9001-certified manufacturer since 2016, we combine advanced engineering with rigorous quality control to ensure every valve meets the highest standards of durability and performance.
Our pressure reducing valve is built to maintain a stable downstream pressure even under fluctuating inlet conditions, protecting sensitive equipment in shipboard systems, desalination plants, and offshore platforms. The all-316L construction not only extends service life but also reduces maintenance downtime, making it a cost-effective choice for long-term marine operations. Below, we break down the key features and technical specifications that set this product apart.
Key Features & Benefits
- Superior Corrosion Resistance: 316L stainless steel body and spring withstand salt spray, acidic fluids, and high humidity, ideal for marine and offshore use.
- Precise Pressure Control: Maintains downstream pressure within ±5% of set point, even when inlet pressure fluctuates up to 10 Bar.
- High Flow Capacity: Optimized internal design minimizes pressure drop and ensures consistent flow rates across the entire size range (DN15–DN100).
- Easy Maintenance: Modular construction allows quick access to internal components without removing the valve from the pipeline.
- Versatile Compatibility: Suitable for water, oil, gas, and other non-corrosive or mildly corrosive media commonly found in marine systems.
- Compact & Lightweight: Space-saving design reduces installation footprint on ships and platforms.

Why Choose Our Marine Grade Pressure Reducing Valve?
When your marine system demands reliability, our valve stands out due to its full 316L stainless steel construction—including the spring. Many competitors use lower-grade alloys for internal components, leading to premature failure. We ensure every wetted part is corrosion-resistant, giving you peace of mind in the harshest environments.
The PN16 rating provides a generous safety margin even at maximum inlet pressure, while the adjustable outlet pressure allows precise tuning for various applications—from freshwater supply to hydraulic control systems. Installation is straightforward, and our valves are compatible with both flanged and threaded piping systems, as per your requirements.
Each valve undergoes hydrostatic testing at 1.5 times the rated pressure and seat leakage tests to ensure zero internal leakage. Our ISO9001 quality management system guarantees consistent manufacturing standards, and every unit is traceable to its production batch.
