  • What is a needle valve / plunger valve?AVK International

    What is a needle valve? Needle valves, sometimes referred to as plunger valves, are regulating valves and enable engineers to finely control and regulate water flow and pressure. The precision is achieved through the fine movement of the shaft, which enables the gearbox to move the piston tube in sliding motion towards opening or closing
