Frequently Asked Questions (FAQ)
-
What is the main purpose of this angle safety valve?
This valve is designed as a protective device for marine cooling water systems. It automatically opens to discharge fluid when the system pressure exceeds a pre-set limit, preventing potential damage to pumps, heat exchangers, and piping. -
Why is bronze the chosen material for this marine valve?
Bronze offers a strong combination of strength and corrosion resistance, which is crucial for withstanding the corrosive nature of seawater and ensuring long-term reliability in marine environments. -
Can this valve be used with fluids other than cooling water?
While optimized for cooling water, it may be suitable for other non-aggressive, compatible liquids within its pressure and temperature limits. Consultation with our technical team is recommended for specific media. -
How do I determine the correct set pressure for my application?
The set pressure must be selected based on the maximum allowable working pressure of your cooling water system. Our team can assist in selecting the appropriate spring range for your needs. -
Are different connection sizes and standards available?
Yes. While the product conforms to the CB907-1994 standard, connection sizes (e.g., DN25, DN40) and types (flanged per ANSI, JIS, or DIN standards, or threaded) can be customized upon request. -
What does the ISO9001 certification mean for this product?
It signifies that our manufacturing processes, from material sourcing to final testing, are managed under a standardized quality system, ensuring consistent product performance and traceability. -
Do you provide testing certificates for the valves?
Functional testing is conducted as part of our quality control. Specific certification, such as a pressure test report, can be provided upon request. -
What is the typical lead time for an order?
Lead times vary based on order quantity and customization requirements. We maintain efficient production scheduling to meet the demands of the global marine industry.
