Needle valve is a type of fine tuning valve with high adjustment accuracy. Its valve plug is needle shaped and mainly used for regulating throttle flow rate. The fine-tuning valve requires the valve port to gradually increase in opening, allowing for continuous and subtle adjustment from closing to opening. The sealing between the valve needle and the valve seat is achieved by the tight fit of its conical surface. The taper of the valve needle has two types: 1:50 and 60 cone angles, and the cone surface is finely ground.
