Manual |
This series of valves are manually driven precision control valves. They are reasonable in structure design, beautiful in
appearance, high precision, small size, practical and reliable, and have good sealing performance. They are used to regulate vacuum and gas flow in vacuum system. The work of the valve is driven by hand turning the adjusting knob, and the needle valve is driven up and down by threaded transmission. The working medium of the valve is air or a few corrosive gases.
