Needle Valves
Overview
Needle valve is a kind of fine-tuning valve. Its valve plug is needle shaped and is mainly used to adjust throttle flow. The fine-tuning valve requires the opening of the valve port to become larger gradually, and can be adjusted continuously and finely from closing to opening.
How Needle Valves Work?
Water faucets are the best example to show how globe valves work. Turning on the faucet means raising or lowering the stem, depending on the design. Water then comes out of the faucet. When turned to the other direction, say, turned off, the raised gate is lowered or the lowered gate is raised.
