High Vacuum Trim Valve

GW-J-T series high vacuum fine-tuning valve (also known as vacuum needle valve) adjusts the gap length between the tapered needle and the hole by screw rotation, and changes the conductance value of the valve seat. It is used to inflate the vacuum system and can precisely adjust the intake flow to control and adjust the vacuum degree in the system. The applicable working medium is air and non-corrosive gas without particle dust.
