As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd specializes in producing high-performance fluid control solutions for demanding global markets. Our CBT3843-1999 Marine Angle Flange Pressure Relief Valve is engineered specifically for marine and offshore applications, where reliability and corrosion resistance are paramount. This valve is designed to provide critical overpressure protection for piping systems, ensuring operational safety and equipment longevity in harsh environments. With an annual export value reflecting our international reach, we combine rigorous ISO9001-certified manufacturing processes with deep industry expertise to deliver valves that meet the stringent requirements of clients across North America, South America, Europe, Asia, Africa, and Oceania.
The core value of this valve lies in its robust construction and specialized finish. It acts as a vital safety component, automatically releasing excess pressure to prevent system failures, leaks, or catastrophic damage. For shipbuilders, oil rig operators, port authorities, and marine equipment suppliers, integrating this valve translates into enhanced system integrity, reduced maintenance costs, and compliance with safety regulations.
Key Product Features & Technical Specifications:
- Marine-Grade Design: Specifically configured for saltwater, humid, and high-vibration environments common in ships, offshore platforms, and coastal facilities.
- Corrosion-Resistant Finish: A specialized surface coating or treatment applied to the valve body and internal components significantly enhances resistance to rust, pitting, and chemical attack, extending service life.
- Angle Flange Connection: The angled flange design facilitates easier installation and integration into complex piping layouts, often saving space and improving accessibility for inspection.
- Precision Pressure Relief Mechanism: The valve is calibrated to open at a predetermined set pressure, providing accurate and repeatable overpressure protection.
- Durable Material Construction: Typically constructed from materials like cast steel for the body and stainless steel for critical trim parts, ensuring strength and durability.
- Reliable Sealing Performance: Designed to maintain a tight seal under normal operating pressures and to reseal effectively after a relief event.

Frequently Asked Questions (FAQ):
-
What is the primary purpose of this Marine Angle Flange Pressure Relief Valve?
This valve is designed as a safety device for marine and offshore piping systems. It automatically opens to discharge fluid (e.g., water, oil, gas) when the system pressure exceeds a preset limit, preventing overpressure damage to pumps, tanks, pipes, and other equipment. -
How does the "corrosion-resistant finish" specifically benefit marine use?
Marine environments are highly corrosive due to saltwater, humidity, and sometimes chemical exposure. The specialized finish on this valve—which could be an epoxy coating, galvanization, or other treatment—creates a barrier that significantly slows rust and corrosion, ensuring the valve's mechanical components function reliably for longer periods. -
Can the pressure relief setting (set pressure) be customized?
Yes. As a manufacturer, we can calibrate the valve to open at a specific pressure required by your system. The standard model reference CBT3843-1999 denotes a design type, but the actual set pressure is customizable based on your technical specifications. -
What are the common flange standards available for this angle flange valve?
We can produce valves with angle flanges conforming to various international standards such as ANSI, DIN, JIS, or GB. The specific standard, flange rating (e.g., Class 150), and dimensions can be tailored to match your existing pipeline connections. -
What materials are typically used for the body and internal parts?
A common construction uses cast steel (like ASTM A216 WCB) for the robust body and stainless steel (such as 304 or 316) for the trim (seat, spring, disc) to resist corrosion. Other material combinations are available upon request to suit different media or environmental conditions. -
Is this valve suitable for other applications besides marine?
While specifically designed for marine conditions, its corrosion-resistant and angle flange features make it a suitable choice for other harsh environments like chemical processing plants near coasts, wastewater treatment facilities, or industrial applications where corrosion and space constraints are concerns. -
How does the ISO9001 certification relate to this product?
Our ISO9001 certification covers our quality management system for manufacturing. It means that processes for design, production, inspection, and testing of this valve are systematically controlled and documented, providing assurance of consistent product quality and traceability. -
What is the typical lead time and shipping process?
Lead time depends on order quantity and customization level. We ship from major ports in China (Shanghai, Guangzhou, Hong Kong, Beijing), offering flexible logistics options to reach your destination efficiently. Specific timelines and shipping methods can be confirmed upon order inquiry.
