The Complex World of Needle Valves

Needle valves are used for regulating the flow of high-pressure fluids and gases within a pipeline. They are so aptly named because their plunger design is similar to that of a sewing needle, and it is this innovative design that allows them to control the flow of fluids and gases with extreme precision. Additionally, they protect delicate gauges from the damage that can be caused by sudden pressure changes.

They can be made from various materials, and the one you choose to use will depend greatly on the specific needs of your application. While they can be made from various materials, they can also be set up to operate manually or automatically. As the premier needle valve manufacturer, CPV Manufacturing offers a wide range of valve products to meet your needs.

Hydraulic needle valves are used to control flow in both directions in a pipeline. Needle valves are comparable to shut-off valves; however, a main distinction between the two types of valves is in the design. Needle valves feature a long plunger that is controlled by a handwheel. The needle valve’s plunger fits into a seat, and this is what gives it the ability to meticulously control the flow of fluids or gases.

Needle valves can be made from a variety of materials. Stainless steel needle valves are frequently used because they are durable, long-lasting, and require little maintenance. They can also withstand extreme temperatures. Brass needle valves are commonly used for instances such as drinking water or high-temperature applications. This type of needle valve is also able to resist corrosion and is a strong material, also making it ideal for chemical processing applications.

CPV Manufacturing is also known for gas needle valve manufacturing and can provide gas needle valves that allow you to closely control gas processes, such as gas mixing applications.
