As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is dedicated to providing reliable and high-performance fluid control solutions for the global marine industry. Our Marine Angle Flange Pressure Relief Valve, designed and manufactured in strict compliance with the CBT3843-1999 standard, represents our commitment to safety, durability, and precision engineering. This valve is engineered to protect critical shipboard piping systems from overpressure conditions, ensuring operational integrity and crew safety. With an annual export value ranging between US$1 Million and US$1.5 Million, our products have gained trust in diverse markets including North America, Southeast Asia, Europe, and Africa, shipped from major ports like Shanghai, Guangzhou, and Hong Kong.
The core value of this pressure relief valve lies in its robust construction and reliable performance under demanding marine conditions. It acts as an essential safety device, automatically releasing excess pressure to prevent system failure or hazardous incidents.
Key Product Features & Technical Advantages:
- Standard Compliance: Manufactured according to the Chinese ship standard CBT3843-1999, ensuring it meets specific requirements for marine applications regarding materials, design, and testing.
- Angle Flange Design: The angled flange connection facilitates easier installation in tight spaces typical of engine rooms and pump chambers, simplifying piping layout and reducing installation time and cost.
- Durable Construction: The valve body is typically constructed from high-grade cast steel or ductile iron, offering excellent resistance to corrosion and mechanical stress. Critical sealing components are often made from stainless steel for long service life.
- Precise Pressure Relief: Features factory pre-set standard pressure settings. The valve is calibrated to open at a precise pressure point, providing consistent and reliable overpressure protection.
- Stable Resealing: Designed to close tightly once system pressure returns to a safe level below the set point, minimizing product loss and preventing unnecessary downtime.
- Low Maintenance: Simple and robust design requires minimal maintenance, which is crucial for marine applications where accessibility can be limited during voyages.

Frequently Asked Questions (FAQ):
-
Q: What is the main purpose of this Marine Angle Flange Pressure Relief Valve?
A: Its primary function is to automatically protect marine piping systems (e.g., for fuel, bilge, or cooling water) from exceeding a safe pressure limit by releasing the excess pressure, thereby preventing equipment damage and ensuring operational safety. -
Q: Can the pressure setting be adjusted on-site after installation?
A: This valve model comes with standard, factory pre-set pressure settings as per the CBT3843-1999 standard. On-site adjustment is generally not intended. For specific pressure requirements, please inquire about customization options during the ordering process. -
Q: Is this valve suitable for use with seawater?
A: Yes, when configured with appropriate materials like cast steel body and stainless steel internals, it offers good corrosion resistance suitable for seawater and other marine fluids. Confirm the exact material grade for your specific fluid service. -
Q: What are the available flange standards and pressure ratings?
A: The valve is built to the CBT3843-1999 standard, which defines its dimensions and performance. Specific flange standards (like JIS, ANSI) and pressure class (PN rating) can be specified upon request based on your system design. -
Q: Do you provide certification for this valve?
A: As a manufacturer with ISO9001 certification, we ensure production under a controlled quality system. Product-specific test reports or certificates of conformity can be provided as per customer request. -
Q: What is the typical delivery time for an order?
A: Delivery time depends on order quantity and specification. For standard models, it is generally shorter. We ship from ports in Shanghai, Guangzhou, or Hong Kong, facilitating efficient logistics to global markets. -
Q: Can this valve be used in applications other than marine?
A: While specifically designed for marine environments per the CBT standard, its robust angle flange design and pressure relief function may be suitable for other industrial applications with similar pressure and media conditions. Consultation is recommended. -
Q: What after-sales support do you offer?
A: We provide technical documentation, installation guidance, and support for spare parts. Our experience in exporting to diverse international markets helps us understand and meet our clients' support needs.
