Product DescriptionProduct DescriptionProduct NameNeedle ValveManufacturing ProcessForgedApplicableOil/Gas/Water/or other mediumNEEDLE VALVEA needle valve is a commonly used type of valve that plays an important role in fluid control systems.In terms of function, it is mainly used to precisely control the flow rate and pressure of fluid. It can achieve fine adjustment of small flow rates, cut off fluid flow to act as a switch, and effectively prevent fluid leakage with its good sealing performance.In terms of application scenarios, needle valves are widely used in industrial fields such as petroleum, chemical industry, electric power, and metallurgy. For example, in laboratory fluid experimental devices, they can precisely adjust the flow rate of reagents; in hydraulic systems, they can control the pressure and flow rate of hydraulic oil to ensure the stable operation of equipment; in addition, they are also quite common in some instruments and meters that require high precision in fluid control.Its working principle is to rotate the valve stem, which drives the valve core (in the shape of a needle) to move up and down in the valve seat. When the valve core moves upward, the gap between the valve core and the valve seat increases, the fluid passage becomes wider, and the flow rate increases; conversely, when the valve core moves downward, the gap decreases, the flow rate decreases until the valve core fits tightly with the valve seat to cut off the fluid. This fine adjustment is based on the precise cooperation between the valve core and the valve seat to achieve precise control of the fluid.
