As a specialized manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our Marine External Thread Bronze Right-Angle Steam Safety Valve, engineered to the rigorous CBT3192-1983 standard. Designed for reliability in demanding marine environments, this valve provides essential overpressure protection for steam systems, ensuring operational safety and equipment longevity. Our commitment to precision manufacturing, backed by nearly a decade of industry experience since 2014, guarantees a product that meets the exacting requirements of global maritime applications. We serve a wide range of markets, from North America and Europe to Southeast Asia and Africa, ensuring our valves are built to perform under diverse operational conditions.
This safety valve is a critical component for any marine steam system, acting as the last line of defense against dangerous pressure build-up. Its right-angle (angle pattern) body design allows for efficient installation in tight spaces and complex piping layouts commonly found on vessels. The use of high-quality bronze ensures excellent corrosion resistance against steam and mild marine atmospheres, contributing to a long service life and reduced maintenance needs.
- Robust Construction & Material: The valve body and critical components are crafted from durable bronze, offering a reliable balance of strength, machinability, and resistance to steam corrosion and dezincification.
- Precise Pressure Relief: Engineered to open at a pre-set pressure and reseat securely once system pressure normalizes, preventing wasteful steam loss and maintaining system efficiency.
- Compact Right-Angle Design: The angle pattern body facilitates easier installation in confined engine room spaces and can help reduce the number of pipe fittings required.
- External Thread Connections: Provide a secure, leak-resistant interface with mating pipelines, simplifying installation and maintenance procedures.
- Standard Compliance: Manufactured in strict accordance with the CBT3192-1983 standard, ensuring compatibility and performance expectations for marine applications.

Frequently Asked Questions (FAQ)
Q1: What is the main function of this valve?
A1: This is a safety relief valve designed specifically for marine steam systems. Its primary function is to automatically release excess pressure from a boiler or pressurized vessel when it exceeds a pre-set limit, preventing potential overpressure failures and ensuring operational safety.
Q2: Can this valve be used for fluids other than steam?
A2: While designed for saturated steam applications up to 250°F, it may be suitable for other compatible gases or liquids within its temperature and pressure ratings. However, for non-steam applications, confirming material compatibility and performance with our technical team is recommended.
Q3: What does "CBT3192-1983" signify?
A3: CBT3192-1983 is a Chinese technical standard pertaining to marine valves. It defines the requirements for design, materials, manufacturing, testing, and inspection for valves used on ships, ensuring they meet specific safety and performance criteria for maritime use.
Q4: Is the set pressure adjustable in the field?
A4: Many models of safety valves allow for blowdown adjustment, but the initial set pressure is typically calibrated and sealed at the factory. Field adjustment of the set pressure is not generally recommended without proper equipment and expertise, as it affects safety calibration. Please inquire about specific adjustment capabilities for your required model.
Q5: What thread standards are available for the external connections?
A5: Common thread standards include NPT (American National Pipe Taper) and BSPP (British Standard Pipe Parallel). The specific thread type and size can be customized based on your piping system specifications. Please provide your connection requirements when inquiring.
Q6: What is the typical lead time for an order?
A6: Lead time depends on the order quantity and specific customization (e.g., set pressure, thread type). Standard configurations may have shorter lead times. We provide reliable shipping from major Chinese ports and can offer an estimated timeline upon receipt of your detailed inquiry.
Q7: Do you provide documentation with the valve?
A7: Yes, typical documentation includes a material certificate and a test report (e.g., shell test, set pressure test) to verify the valve's performance and compliance with specifications. Certificates of conformity can be provided upon request.
Q8: How does the right-angle design benefit installation?
A8: The right-angle (or angle pattern) body allows the inlet and outlet ports to be oriented 90 degrees apart. This design can simplify piping layouts, reduce the need for additional elbows, and save valuable space in compact marine engine rooms, making installation more efficient.
