A flow control valve includes an inlet and an outlet through which fluid enters and exits the valve. A valve plunger has a guide spring attached thereto, such that the guide spring is situated between the plunger and a valve orifice. The plunger, and thus the guide spring, is movable relative to the orifice to control fluid flow through the valve. The guide spring and the orifice surface adjacent the guide spring define coplanar surfaces that seal against each other when the valve is closed.
Une vanne de commande d'écoulement comprend une entrée et une sortie à travers lesquelles le fluide entre et sort de la vanne. Un piston de vanne possède un ressort de guidage fixé sur celui-ci, de sorte que ce ressort de guidage soit situé entre le pistons et un orifice de la vanne. Ce piston et, par suite ce ressort de guidage, est mobile par rapport à l'orifice de façon à commander l'écoulement de fluide à travers la vanne. Ce ressort de guidage et la surface de l'orifice contiguë à ce ressort de guidage définissent des surfaces coplanaires qui se collent ensemble lorsque la vanne est fermée.
