An example might be that as the cylinder extends, it contacts the roller, which switches the valve and this stops the cylinder stops moving. The top symbol shows a two-position valve that is switched by a mechanical roller. This means they have three flow pipe connections. The valves shown are all three-way valves. Not all valves will operate or work safely without a low-pressure drain signal. When using valves that switch pressure lines, without a direct, low pressure, return line connection it is important to make sure that the valves solenoid and spring chambers are rated for the maximum pressure they may see. The bottom symbol shows a hydraulically operated valve, but in this case, flow can only pass in one direction because the spring chamber is connected to the low pressure, return line connection. The middle symbol shows an electrically operated valve which is 'Normally Open' (NO). When activated the left-hand box would be connected to the pipes and flow could pass through the valve. in its standby condition, the right-hand box is connected to the pipes and no flow can pass through (closed). This top valve, therefore, shows a 'Normally Closed' (NC) valve e.g. pushed over by the spring, not the solenoid. Valves should always be drawn in the de-activated position e.g. The double arrow in the left box shows that the flow may pass in both directions. The top symbol shows a manually activated valve that is pushed over against a spring. This means they have two flow pipe connections and can switch into two different positions. The valves shown are all two way, two position directional valves.

In the United States, the American National Standards Institute (ANSI) is responsible for symbol information. A family of graphic symbols has been developed to represent fluid power components and systems on schematic drawings. Actuator always pushes and never pulls the spool. Number of ports tells how many pipes can be connected to the valve. In the above symbol two square boxes are there so it is a two position valve. Tips for reading directional control valve symbol: The number of boxes shown in the valve symbol is the number of positions for the valve. Available in SVG, PNG, JPG, DXF & DWG formats.
