High Pressure Needle Valves

Product Specification

Product Description

Needle valve is a high-pressure valve that consists of a body, cylinder, piston, flow regulators, shaft, and gears. It cannot be used in sewage media but can be used for any purpose as long as it is clean water media. However, the main area of usage is the conditions where the butterfly valve or gate valve cannot be used. As a parameter of geometric design, there is a water-drop shaped chamber in the middle of needle valve. As flow travels around that chamber, section of flow turns into a ring. As it continues, flow is forced to be directed at centre at outlet side of valve. Cavitation occurs and finishes inside the flow and does not create any damage on valve or other equipment. Operation of Needle Valve, By means of a mechanism, piston moves forwards and backwards inside the cylinder. When piston moves into the cylinder, flow begins through the space between body and cylinder. Valve is open at that position.
