Related Information

Hydraulic needle valves are valves that use a small, pointed needle to regulate the flow of fluids in a hydraulic system. They are often used to control the flow of high-pressure fluids in applications such as hydraulic machinery, oil rigs, and aircraft landing gear systems.
Needle valves have a long, narrow stem with a pointed tip that fits into a seat in the valve body. As the stem is turned, the pointed tip opens or closes the flow of fluid through the valve. The valve's flow can be finely adjusted by turning the stem, which allows for precise control of the fluid flow.
Hydraulic needle valves are typically made from materials such as stainless steel, brass, or aluminum, and are designed to withstand high pressures and temperatures. They are commonly used in applications where a small, precise flow of fluid is needed, such as in the control of hydraulic cylinders or actuators.
There are several types of hydraulic needle valves, including standard needle valves, adjustable-stem needle valves, and manifold-mounted needle valves. Each type is designed for specific applications and has its own unique features and benefits.
It is important to select the appropriate needle valve for your specific application to ensure proper function and to prevent damage to the valve or other components in the system. It is also important to follow the manufacturer's instructions for installation, maintenance, and repair to ensure the valve is operating correctly and safely.
