As a professional manufacturer with a strong commitment to marine safety, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Screw End Boiler Relief Valve, meticulously crafted to the stringent CB/T3192-1983 standard. Established in 2016 and backed by ISO9001 certified quality management, we specialize in providing reliable pressure management solutions for the global maritime industry. This valve is engineered to offer dependable overpressure protection for marine boiler systems, ensuring operational safety and compliance in challenging sea environments. Our focus on precision manufacturing and durable bronze construction delivers a product that shipbuilders and marine engineers can trust for critical applications.
This valve is a cornerstone of marine boiler safety, designed to automatically release excess pressure to prevent catastrophic equipment failure. Its robust construction and adherence to specific maritime standards make it an indispensable component for any vessel.
- Superior Bronze Construction: The valve body is manufactured from high-grade bronze, chosen for its excellent corrosion resistance against seawater, steam, and marine atmospheres. This material ensures long-term durability and reliable performance, reducing maintenance frequency and lifecycle costs.
- Precise Pressure Relief Mechanism: Engineered to activate at a pre-set pressure threshold, the valve provides a fail-safe release of excess pressure from the boiler system. This precise operation is critical for maintaining system integrity and protecting expensive boiler equipment from damage.
- Standard-Compliant Design: Manufactured in strict accordance with the Chinese CB/T3192-1983 standard for marine boiler relief valves. This compliance guarantees that the valve meets recognized specifications for dimensions, performance, and materials, facilitating regulatory approval and installation confidence.
- Screw End Connection: Features threaded (screw end) connections for secure and straightforward installation into marine boiler piping systems. This design allows for a tight seal and easy integration, minimizing installation time and potential leak points.
- Reliable Sealing Performance: Utilizes high-quality sealing components designed to withstand high temperatures and pressures typical of boiler operations. This ensures a tight seal during normal operation and a clean, effective release when activated.

Frequently Asked Questions (FAQ):
Q1: What is the primary function of this Marine Screw End Boiler Relief Valve?
A1: Its primary function is to act as a safety device on marine boilers. It automatically opens to discharge excess pressure (steam or hot water) if the pressure exceeds a pre-set limit, preventing potential boiler explosions or damage.
Q2: Why is bronze specified as the body material for this valve?
A2: Bronze offers superior corrosion resistance in marine environments, effectively withstanding exposure to seawater, salt-laden air, and steam. It also provides good machinability for precise manufacturing and durability under thermal cycling.
Q3: What does "CB/T3192-1983" signify, and why is it important?
A3: CB/T3192-1983 is a Chinese national professional standard specifically for marine boiler relief valves. Compliance ensures the valve meets defined criteria for design, materials, dimensions, and performance, which is often required for vessel classification and regulatory approval.
Q4: Can the pressure setting (opening pressure) of this valve be adjusted?
A4: The pressure setting is typically pre-set at the factory according to customer specifications or standard ratings. It is designed for a specific set point to ensure accurate and reliable operation. Custom set pressures are available upon request.
Q5: Is this valve suitable for use with media other than steam?
A5: While designed primarily for steam service in boiler applications, it may be suitable for other compatible hot water or gas services. It is crucial to confirm the specific media compatibility with our technical team before such applications.
Q6: What are the main installation considerations for this screw-end valve?
A6: Ensure the pipe threads match the valve's threads (e.g., NPT, BSP). Use appropriate sealant or thread tape compatible with the operating temperature and medium. Install the valve in an accessible, upright position as per boiler system design, and follow all relevant marine engineering installation guidelines.
Q7: Do you offer different sizes or pressure ratings for this valve model?
A7: Yes, we can provide variations in nominal size (DN) and pressure class (PN) to match different boiler system designs. Please provide your specific requirements for a tailored quotation.
Q8: What kind of testing is performed on these valves before shipment?
A8: Our valves undergo rigorous factory testing, which typically includes shell strength tests and seat leakage tests to verify pressure integrity and sealing performance, ensuring they meet the specified standards before delivery.
