Frequently Asked Questions (FAQ):
Q1: What is the main purpose of this angle safety valve?
A1: Its primary purpose is to automatically release excess pressure from marine systems (like boilers or pressure vessels) to prevent equipment damage and ensure safety. The angle design helps it fit into piping layouts where a straight-through valve cannot.
Q2: Does the CB304-1977 standard apply internationally?
A2: CB304-1977 is a Chinese marine industry standard. It is widely recognized and accepted, particularly for vessels built or serviced in Asian markets and by international operators familiar with these specifications. It signifies the valve is built to defined technical criteria for marine use.
Q3: What is included in the "extended warranty" offer?
A3: The extended warranty provides coverage beyond our standard warranty period. Specific terms, such as duration and what is covered (e.g., material defects, workmanship), can be discussed and confirmed upon order placement.
Q4: Can this valve be used with fluids other than water?
A4: Yes, it is suitable for common marine media such as steam, air, and oil, provided the fluid is compatible with cast iron and within the valve's pressure and temperature ratings. For aggressive chemicals, alternative materials may be suggested.
Q5: How do I determine the correct set pressure for my application?
A5: The set pressure must be based on the maximum allowable working pressure (MAWP) of the system it is protecting. We require this information to calibrate the valve's spring accordingly before shipment. Our technical team can assist with this calculation.
Q6: What are the available port sizes and connection types?
A6: Port sizes and connection types (e.g., flanged dimensions, thread standards) are customizable. Please provide your system's piping specifications when inquiring, and we will confirm the available options.
Q7: Do you provide testing certificates with the valve?
A7> Yes, as a standard practice, we can provide factory test reports for the set pressure and seat tightness. Specific certification requirements should be specified at the time of order.
Q8: What is your typical lead time for this product?
A8: Lead time depends on order quantity and any customization required (like specific set pressure). Standard configurations generally have shorter lead times. We provide an estimated timeline with every quotation.
