Plunger flow control valve
Art. F500-F550-F560
Application field
The PLUNGER FLOW CONTROL VALVE is mainly designed for the water flow regulation in a pipeline. The adjustment, takes place by axial displacement of a cylindrical shutter, actuated by a shaft-connecting rod-crank mechanism.
General informations
The needle-valve is mainly designed for the water flow regulation in a pipeline. The flow regulation happens through the axial movement of a piston, operated by a rod and crank mechanism.
The piston is positioned in the center of the body valve and steers in a chamber properly shaped in order to avoid noises and cavitations damages. This characteristic confers to the valve regular operation free from vibrations.
The water flow is guided in a annular chamber around the streamlined central body. The cross section of this chamber is continuously reducing from inlet to the throttle. This causes continuous rises of flow speed and fall of the pressure. The geometrically ideal design, confines the cavitations bubbles in the center of the outlet mouth, avoiding damages to the valve.
