Product Spotlights
As a specialized manufacturer with a strong focus on marine and industrial valve solutions since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents the CB3022 Stainless Steel Safety Valve. Engineered specifically for the demanding environment of marine compressed air systems, this valve is a critical component for ensuring operational safety and system integrity on vessels worldwide. Our commitment to quality, backed by our ISO9001 certification, ensures that every CB3022 valve meets rigorous standards for reliability and performance. With an annual export value reflecting our global reach across continents from North America to Oceania, we understand the diverse needs of the maritime industry and deliver products that shipbuilders, system integrators, and vessel operators can depend on.
The CB3022 is designed to automatically release excess pressure from compressed air systems, preventing catastrophic failures and protecting expensive downstream equipment. Its robust stainless steel construction offers superior corrosion resistance against saltwater atmospheres, a fundamental requirement for all marine applications.
- Superior Corrosion Resistance: Fabricated from high-grade stainless steel (304 or 316), the CB3022 valve body and internal components are inherently resistant to rust and corrosion caused by salty, humid marine air. This material choice significantly extends the valve's service life compared to carbon steel alternatives, reducing maintenance frequency and total cost of ownership.
- Precise and Reliable Pressure Relief: At the heart of the valve is a precision-engineered spring mechanism. This mechanism is factory-set to a specific cracking pressure. When system pressure exceeds this pre-set limit, the valve opens instantly and proportionally to vent the excess pressure. Once pressure normalizes, it reseals tightly, minimizing air loss.
- Robust Construction for Harsh Environments: Beyond material selection, the valve features a sturdy design with high-integrity seals (available in PTFE, NBR, or EPDM) that maintain their properties across a wide temperature range from -20°C to +150°C. The design accounts for vibration and movement common on ships.
- Easy Installation and Maintenance: The CB3022 is available with standard threaded (NPT, BSP) or flanged connections for straightforward integration into existing piping. Its design often allows for in-line testing and, in many models, adjustment or maintenance of the spring setting without removing the entire valve from the line.
- Versatile Application Range: While designed for marine compressed air, its robust build makes it suitable for other onboard systems using inert gases or for similar industrial applications in coastal or corrosive environments.

Frequently Asked Questions (FAQ)
Q1: What is the main purpose of this safety valve on a ship?
A1: Its primary function is to protect marine compressed air systems (like those for control air, starting air, or service air) from exceeding safe pressure limits. It automatically opens to vent excess pressure, preventing potential damage to air receivers, piping, and connected equipment, which is critical for vessel safety.
Q2: Why is stainless steel important for a marine safety valve?
A2: The marine environment is highly corrosive due to saltwater spray and humidity. Stainless steel (grades 304 or 316) offers excellent resistance to this corrosion, ensuring the valve body and mechanism remain functional and leak-free over a long service life, unlike materials that may rust and fail.
Q3: Can the pressure setting be adjusted on-site?
A3: This depends on the specific model. Some CB3022 valves are designed with an adjustable spring setting that can be calibrated within a range using special tools. Others are factory-set and sealed. It's important to specify your requirement for adjustable or fixed setting when ordering.
Q4: Is this valve suitable for other gases besides air?
A4: The CB3022 is primarily designed for compressed air and other compatible inert gases like nitrogen. It is not typically recommended for flammable, toxic, or highly reactive media without consulting the manufacturer first, as seal compatibility and design may need review.
Q5: What certifications does this product have?
A5: Our manufacturing process is certified under the ISO9001 Quality Management System, ensuring consistent production quality. For specific marine classification society approvals (like ABS, DNV, LR, etc.), please inquire as these are often project-specific and can be arranged upon request.
Q6: What are the available port options for shipment?
A6: We ship regularly from major Chinese ports including Shanghai, Guangzhou, Hong Kong, and Beijing, offering flexibility to optimize logistics and costs for our international customers across our main global markets.
Q7: How do I determine the correct size and pressure setting for my application?
A7: You will need to know your system's maximum working pressure, required relief capacity (flow rate in SCFM or NM³/h), and inlet/outlet pipe size. Our technical team can assist you in selecting the appropriate CB3022 model based on these parameters.
Q8: What is the lead time for an order?
A8: Lead times vary based on order quantity, specification (standard vs. custom), and current production schedule. Standard models typically have shorter lead times. We provide estimated delivery schedules with every quotation to help you plan your project.
