needle valve Model: DF-LOK Needle Valves are similar in structure to Globe Valves, with the difference that instead of a disc plate, it has a long cone-shaped part similar to a needle at the end of the main rod of the valve. The needle valve, which takes its name from the shape of the disc and its seat, is part of the ball valve family in terms of construction and operation. With these valves, you can establish precise control of fluid flow, especially in narrow and delicate pipes. The structure of the needle valve is such that the current is directed to a small hole and after turning 90°, it is directed to the tip of a cone, and as it can be seen from the figure, the current flows through this hole and a needle-shaped piece to the outlet. The disk of the needle valve consists of a thin conical rod that passes through the circular hole of the plate and limits the movement of the fluid. The construction of these valves is mostly used in carburetors. Needle valves are very delicate and almost small in terms of structure, and due to having a reliable mechanism, they are used in sensitive and precise operations. It is widely used in oil or petrochemical laboratories and precision instruments. The diameter of needle valves usually does not exceed 2 inches, and needle valves are mostly used in places where restrictions are necessary, and restrictions mean time delay and slow pressure changes. Needle valves are divided into female needle valve, male needle, tube end needle valve and female male valve based on the type of connection.
