As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is dedicated to providing high-quality fluid control solutions. Our CBT3843-1999 Marine Angle Flange Pressure Relief Valve is engineered to meet the rigorous demands of marine applications, ensuring the safety and reliability of your shipboard systems. We combine robust manufacturing capabilities, established in 2016, with comprehensive technical support to deliver a product that offers exceptional performance and peace of mind. This valve is a critical safety component designed to protect expensive equipment from overpressure damage, making it an indispensable part of any marine engineering project.
The valve's core value lies in its precise pressure regulation and durable construction, tailored specifically for the harsh marine environment. Let's delve into the detailed features and specifications that set this pressure relief valve apart.
Key Features and Advantages:
- Strict Compliance: Manufactured in strict accordance with the Chinese ship standard CBT3843-1999, ensuring compatibility and reliability for marine vessel installations.
- Robust Angle Flange Design: The angle-type flange connection facilitates easier installation in tight spaces and allows for direct piping layout, reducing potential leak points compared to inline designs.
- Durable Material Selection: The main body is typically constructed from high-grade cast steel or ductile iron, with internal trim like the seat and disc made from corrosion-resistant stainless steel, offering excellent resistance to seawater and marine atmospheres.
- Precise Spring-Loaded Mechanism: Utilizes a calibrated spring mechanism to provide accurate and repeatable pressure relief. The set pressure can be adjusted within a specified range to match system requirements.
- Reliable Sealing: Designed to provide tight shut-off up to the set pressure and to reseat effectively after relieving overpressure, minimizing media loss and maintaining system integrity.
- Comprehensive Technical Support: Our technical team provides assistance with selection, installation guidance, and troubleshooting, ensuring optimal valve performance throughout its service life.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of an angle flange design compared to a straight-through design?
A: The angle flange design allows the inlet and outlet to be oriented at 90 degrees. This is particularly useful in space-constrained marine engine rooms as it can simplify piping runs, support the weight of the valve more effectively, and often allows for easier maintenance access. -
Q: Can this valve be used for media other than water?
A: Yes. While commonly used for water systems, it is suitable for various media typical in marine applications, including oil, air, and steam. The specific material selection for body and trim can be tailored to ensure compatibility with your specific media. -
Q: How is the set pressure determined and adjusted?
A: The set pressure is determined by the calibration of the internal spring. We provide valves with springs set to your specified relief pressure. Adjustment, if required within the spring's range, can be performed using the adjustment mechanism, which should be done by qualified personnel following proper procedures. -
Q: Does compliance with CBT3843-1999 make this valve acceptable for international ship registries?
A: The CBT3843-1999 is a Chinese shipbuilding standard. While it indicates a robust design for marine use, acceptance by specific international registries (like Class societies: DNV, ABS, LR, etc.) may require additional certification or review. We can provide documentation to support such approval processes upon request. -
Q: What kind of technical support do you offer?
A: Our technical support includes assistance in selecting the correct valve size, pressure rating, and material for your application; providing installation and maintenance guidelines; and offering troubleshooting advice. We aim to be a resource throughout the valve's lifecycle. -
Q: What are the available flange standards and face types?
A: We typically manufacture flanges to common international standards such as ANSI/ASME or DIN/JIS, with face types like Raised Face (RF) or Flat Face (FF). The exact standard can be specified at the time of ordering to ensure compatibility with your existing piping. -
Q: What is the typical lead time for an order?
A: Lead times vary based on order quantity, specifications, and current production schedule. Standard configurations may have shorter lead times, while customized orders may require additional engineering and manufacturing time. We provide estimated lead times with every quotation. -
Q: Do you provide spare parts for this valve model?
A: Yes, we supply genuine spare parts such as springs, seals (gaskets), discs, and seats. Using original spare parts is recommended to maintain valve performance and warranty conditions.
