<p>The electromagnetic pressure limit valve (1), for a hydraulic/pneumatic system, has a cylindrical pressure spring assembly (5,6) to hold the armature piston (10) against a lifting movement to close the inflow and outflow (2) under normal conditions. The spring assembly has a push rod (3,4) at each spring. When the magnet (8) is energized, a spring (5) is moved away from the seal (7) and the other spring (6) acts on the seal with a lower nominal pressure.</p> |
