FAQ’s About Copper Nickel 90/10 Needle Valve
Copper Nickel is primarily used in marine and seawater applications because of its excellent corrosion resistance, biofouling resistance, and durability. It is commonly used for valves, heat exchangers, condensers, piping systems, shipbuilding, and desalination plants.
A needle valve is used to precisely control the flow of liquids or gases in a pipeline. Its fine-threaded stem and needle-shaped plunger allow accurate regulation, making it ideal for instrumentation, sampling lines, and high-pressure systems.
Yes. A needle valve can indirectly control pressure by regulating the flow rate, allowing smooth and steady pressure adjustment. It helps prevent sudden surges and maintains accurate flow control in hydraulic, chemical, and gas applications.
The pressure range depends on the material and design, but most industrial needle valves can handle up to 6,000 psi, and high-pressure models can reach 10,000–15,000 psi or more. Copper Nickel 90/10 needle valves are commonly used in high-pressure marine and industrial systems.
