Just like every other industrial valve, needle valve's purpose is to control flow. It shares similarity in design with globe valve. Needle valve regulates the flow of liquids and gases at low flow rates. Of many needle valves, our company brings to the market hydraulic, mini and pneumatic needle valves. To determine the right valve for specific application, the factors which need to be taken into consideration are pressure rating, valve size, operating temperature and material used in construction. The pressure rating ranges from 5000 upto 10000 psi at temperature of 100 degree Fahrenheit. The valves are designed in different sizes and end connection options. This kind of valve is available in metric sizes ranging from 2-11 mm and standard sizes, from 1/8 to 1 inch. It is important to select the right size, because it would impact the system's operations efficiency and chances of leakage.
- Needle valves are purposely smaller in size, as it allows finest flow control. These valves are designed to function in all temperatures and conditions.
- Material used for the fabrication of needle valve can be stainless steel, carbon steel, bronze or brass.
- The major application of this kind of valve is in delicate gauges.
- It can also be found in many industries for applications that require control of air, gas, steam, oil, water and non viscous liquid.
