HHV’s manually operated Needle Valves are suited for admitting defined, clearly reproducible gas streams into a vacuum chamber.
Needle Valve consists of a Brass housing a regulating needle of stainless steel and a valve seat made of Brass.
In closed position, the needle is passed against the conical valve seat by a pressing spring. The needle moves in the axial direction. It is coupled to the actuating knob over a ball bearing.
