1/2 NPT Female Thread Needle Valve SS316L 10000PSI Oilfield Needle Valve

Manifold Control Valve – Needle Valve Description
Needle valve is a fine-tuning valve with a needle-shaped valve plug, which is mainly used to adjust the air flow. The fine-tuning valve requires the valve opening to gradually become larger, and the maximum can be continuously and finely adjusted from closing to opening. The needle valve plug can achieve this function. Needle valve plugs are generally made of quenched steel long needles, while the valve seat is made of soft materials such as tin and copper. The seal between the valve needle and the valve seat is achieved by the tight fit of its conical surfaces. The taper of the valve needle has two taper angles: 1:50 and 60, and the taper surface should be finely ground. The sealing between the valve stem and the valve seat is realized by the bellows.
