Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our SS316L Marine Nitrogen Regulator with Safety Relief Valve — a precision-engineered solution designed for critical marine nitrogen control systems. As a manufacturer established in 2016 with ISO9001 certification and annual export value exceeding US$1 million, we combine advanced machining technology with rigorous quality control to deliver zero internal leakage performance. This regulator is specifically built to withstand harsh marine environments while providing reliable pressure regulation for nitrogen blanketing, inerting, and pneumatic applications. With its integrated safety relief valve and corrosion-resistant SS316L construction, it offers unmatched safety and durability for demanding offshore and shipboard operations.
Our SS316L Marine Nitrogen Regulator is engineered to meet the highest standards of precision and reliability. The zero internal leakage design ensures that no gas escapes even under prolonged static conditions, which is critical for maintaining system integrity and preventing oxygen ingress. The safety relief valve is factory-set to your specified pressure and can be easily adjusted in the field. Below are the key technical specifications:
| Parameter | Value |
| Material | SS316L (1.4404) |
| Maximum Inlet Pressure | 3000 psi (customizable) |
| Outlet Pressure Range | 0–150 psi (other ranges available) |
| Relief Valve Setting | Adjustable, typically 10% above outlet set point |
| Internal Leakage | Zero (bubble-tight shut-off) |
| Connection Type | NPT, BSP, or as required |
| Operating Temperature | -20°C to +80°C |
| Certification | ISO9001 |
Product Features & Benefits
- Zero Internal Leakage: Our proprietary sealing technology ensures that the regulator remains bubble-tight even after thousands of cycles. This eliminates gas waste, prevents pressure drop, and enhances safety in confined marine spaces.
- SS316L Construction: The entire body, spring, and internal components are made of SS316L stainless steel, offering superior resistance to chloride-induced corrosion, salt spray, and acidic environments. This extends the product lifespan significantly compared to standard brass or carbon steel regulators.
- Integrated Safety Relief Valve: The built-in relief valve provides overpressure protection, automatically venting excess pressure to prevent system failure. It is factory-calibrated and can be re-adjusted on-site without disassembly.
- Marine-Grade Design: All external surfaces are passivated and electropolished to resist biofouling and corrosion. The regulator is suitable for use in engine rooms, nitrogen blankets, and inert gas systems on ships, oil platforms, and offshore installations.
- High Flow Capacity: Optimized valve seat and port design allow for high flow rates with minimal pressure drop, ensuring stable outlet pressure even under fluctuating inlet conditions.
- Low Maintenance: The self-cleaning seat design reduces the need for frequent servicing. All seals are made of compatible elastomers for nitrogen service, and the regulator can be easily overhauled in the field.
- Customizable Options: We offer a range of inlet/outlet port sizes, pressure ranges, and connection types (NPT, BSP, flange) to meet specific customer requirements. Gauge ports and panel-mount brackets are also available upon request.
Why Choose Our SS316L Marine Nitrogen Regulator?
Compared to conventional regulators, our product delivers zero internal leakage — a critical advantage for applications where even a tiny leak can cause contamination or safety hazards. The SS316L material ensures long-term durability in the most aggressive marine environments. The integrated safety relief valve eliminates the need for separate external relief devices, saving space and installation cost.
Our manufacturing process includes 100% helium leak testing on every unit to verify zero internal leakage. Each regulator is also pressure-tested at 1.5 times the rated working pressure. This rigorous quality control, combined with ISO9001 certification, guarantees consistent performance batch after batch.
Frequently Asked Questions
-
Q: What is the internal leakage rate of this regulator?
A: The regulator is designed for zero internal leakage (bubble-tight). We perform helium leak testing to ensure no measurable leakage under static conditions. -
Q: Can this regulator be used with other gases besides nitrogen?
A: Yes, it is compatible with inert gases such as argon, helium, and compressed air. However, for reactive gases, please consult our engineering team for compatibility. -
Q: Is the safety relief valve adjustable?
A: Yes, the relief valve set pressure can be adjusted within a range. The default setting is typically 10% above the outlet pressure set point, but we can factory-set to your specific requirement. -
Q: What is the maximum inlet pressure?
A: Standard rating is up to 3000 psi. Higher pressure versions are available upon request. -
Q: Does the regulator come with a gauge?
A: Gauges are not included as standard, but we offer optional gauge ports and can install pressure gauges per your specification. -
Q: What certifications does this product have?
A: Our manufacturing facility is ISO9001 certified. The regulator itself is designed to meet relevant marine and industrial standards. Specific certifications (e.g., DNV, ABS) can be discussed for large orders. -
Q: How do I select the correct port size?
A: The most common sizes are 1/4" NPT or BSP. We can customize to 3/8", 1/2", or larger. Please provide your piping system details for recommendation. -
Q: What is the lead time?
A: Standard models ship within 2–3 weeks. Custom orders may require 4–6 weeks depending on complexity.
