Frequently Asked Questions
What are brass needle straight valves with both female ends used for?
These valves are used to precisely regulate the flow of liquids and gases in marine piping systems, including fuel lines, cooling water circuits, and gauge lines. They are also used in industrial applications where fine throttling and reliable shut-off are required.
What connection sizes are available?
Standard sizes include 1/4 inch, 3/8 inch, and 1/2 inch. Both inlet and outlet connections have female threads, and NPT or BSPT threading is available. Custom sizes can be ordered on request.
Can these valves handle high-pressure applications?
Yes, the brass body and needle-type stem allow working pressures up to 500 psi (3.5 MPa). Always verify the pressure rating of the complete system and ensure the valve is used within its rated limits.
Are brass needle valves suitable for saltwater environments?
Brass is a corrosion-resistant alloy, but prolonged exposure to saltwater may affect it. These valves are ideal for marine applications, but consider additional material protection if the valve is in continuous contact with raw saltwater.
