Product Features

Adopt fine thread structure, high adjustment precision.
The shaft seal is made of fluorine rubber, and the valve body is welded with stainless steel, so the leakage rate is small.
Needle and stem are separated and equipped with ball seat at the connection, which prolongs the service life of needle valve and valve seat, and is convenient for maintenance.

Product Description

This series of valves are manually driven precision control valves with reasonable structural design, beautiful appearance, high precision, small size, reliable use, good sealing performance, etc. They are used to regulate the vacuum degree and gas flow in vacuum systems. The work of the valve is powered by hand turning the adjusting knob, and the needle valve is lifted and lowered by the thread drive. The working medium of the valve is air or a few corrosive gases.
