Gw-j-t series high vacuum fine tuning valve (also known as vacuum needle valve) is to adjust the gap length between the conical needle and the hole and change the flow conductivity of the valve seat by rotating the screw. It is used to charge the vacuum system and precisely adjust the intake flow to control and adjust the vacuum degree in the system.
The applicable working medium is air without particle dust and non corrosive gas.
