Control Valve Symbol

The symbol for directional control valve is made of number of square boxes adjacent to each other depending on the number of positions Connections to the valve are shown on these squares by capital lettersusually they are named only in their normal position and not repeated in other positionsactuation system of the valve is also designated.

Control valve symbol. Symbol Via electric stepper motor Via solenoid, e g with two counteracting solenoids Nonreturn valve without spring Quick exhaust valve Shuttle valve Oneway flow control valve, adjustable Nonreturn valve with spring Dualpressure valve Via solenoid or manual override and pilot valve Flow control valve Nonreturn valve Connection. ISA SYMBOLOGY The symbology for the identification of the measurement and control instrumentation on the flow and process diagrams and on the P&ID (Piping & Instrument Diagram), commonly called P&I (Piping & Instrumentation), is generally compliant with the Standard ISA (Instrumentation Society of Automation) identified as S5, that is composed of identification codes and graphic symbols.

Control valves are symbolized by combining the appropriate valve symbol and actuator symbol, as illustrated in Figure 2 Control valves can be configured in many different ways The most commonly found configurations are to manually control the actuator from a remote operating station, to automatically control the actuator from an instrument. 2 interlock number and proper symbol (dcs or plc) will be shown on process p&id 3 for valves located in pits with extended valve stems / actuators, limit switch and positioner will be located outside the pits 4 safety solenoid valve (sy) is to trip the valve to its failure position 5. Control valve symbol is incorrect and the substitution palette shows instrument symbols Note This may occur after making a substitution of the valve body symbol.

Schematic symbols are used to identify and graphically depict the function of fluid power components Recognizing and understanding schematic Valves control the direction and amount of flow while actuators are the work producers such as cylinders and rotary actuators. Control is shown by normal actuation symbols in Figure 48b, for example, the spring pushes the valve right, decreasing flow, and pilot pressure pushes the valve left, increasing flow This represents a pressurerelief valve which would be connected into a hydraulic system as shown in Figure 48c. Control valve symbol is incorrect and the substitution palette shows instrument symbols Note This may occur after making a substitution of the valve body symbol.
