Normally closed hydraulic valve schematic
Web14 de out. de 2024 · When we see a spool valve schematic, we can see it is made up of boxes, each containing a number of lines and arrows. The number of boxes that make up a valve symbol indicates the number of possible positions the valve has. Flow direction is indicated by the arrows in each box. These arrows represent the flow path the valve … WebThe valves shown are all two way, two position directional valves. This means they have two flow pipe connections and can switch into two different positions. The top symbol shows a manually activated valve that is pushed over against a spring. The double arrow in the left box shows that the flow may pass in both directions.
