Abstract
A valve, in particular a pilot-operated proportional directional poppet valve, has a valve housing () with a fluid inlet () and a fluid outlet (). The fluid stream between the fluid inlet () and the fluid outlet () is adjustable by a main piston (). A pilot valve chamber () on a rear face () of the main piston () has a pilot valve closing member () movable by an actuating device () to adjust the fluid stream between the pilot valve chamber () and the fluid outlet (). A supply aperture () is between the fluid inlet () and the pilot valve chamber (). The opening cross-section of the supply aperture () can be reduced by a control element ().
