一、GW-J-T型系列高真空微调阀概述

GW-J-T型系列高真空微调阀(又称真空针阀)是靠螺杆传动来调节锥形针和孔的缝隙长度，改变阀座流导值。是用来向真空系统中充气并可精确调节进气流量，以控制和调节系统内的真空度。
适用的工作介质为不含颗粒灰尘的空气及非腐蚀性气体。

The GW-J-T series high vacuum fine adjustment valve (also known as vacuum needle valve) is driven by a screw to adjust the gap length between the conical needle and the hole, and change the valve seat flow conductivity value. It is used to inflate the vacuum system and accurately adjust the intake flow rate to control and regulate the vacuum degree inside the system.

The applicable working medium is air without particulate dust and non corrosive gases.
