Frequently Asked Questions
What are the typical applications for these brass needle valves?
These valves are commonly used for precise flow adjustment in marine fuel systems, hydraulic circuits, cooling water lines, and pressure instrumentation aboard ships and offshore installations.
Are these valves suitable for seawater service?
Yes, the marine-grade brass construction offers good corrosion resistance in salty air and seawater splash zones, making them suitable for many deck and engine room applications.
What does BSP thread mean?
BSP (British Standard Pipe) is a common thread standard for pipe fittings. These valves have parallel threads, designated as BSPP or G, which seal with a washer or O-ring when properly installed.
Can I use these valves with both liquids and gases?
Yes, they are designed for both liquid and gas service, provided the operating pressure and temperature are within the rated limits. Always verify compatibility with the specific media.
