Solenoid Control Valve Symbol

3 2 way solenoid valve symbols.

Solenoid control valve symbol. A solenoid valve is an electromechanically operated valve. For multi port valves such as 3 way and 4 way the structure of the symbol is similar having a triangle to represent each port or way. Here is a list of symbols for various types of valves used in process industry. Symbols show the methods of actuation the number of positions the flow paths and the number of ports.

2 way directional control valves a 2 way directional valve has two ports normally called inlet and outlet. Many types of valves are required in a process plant for flow regulation or on off purpose. The symbols below show different circuit functions of 3 2 way valves. Solenoid valves differ in the characteristics of the electric current they use the strength of the magnetic field they generate the mechanism they use to regulate the fluid and the type and characteristics of fluid they control.

The number of positions are decided by the number of boxes. Use the box to indicate the working position of the solenoid valve. Valve symbols including solenoid valve symbols are those that are in common use. Understanding ansi iso schematic symbols for fluid power and pneumatic components are used to identify and graphically denote the function and operation of piped control systems.

For example the ato 2 position 3 way solenoid valve means that there are two. Most valve symbols have three parts see. This article deals with common solenoid valve and other pneumatic symbols giving a detailed view of pneumatic circuit symbols and their meaning. P id symbols for control valve assembly and following actuators manual diaphragm spring type solenoid pilot motor electro hydraulic etc.

These valves can be used for multiple applications such as switching between two circuits or actuating a hydraulic cylinder. Here is a brief breakdown of how to read a symbol. Type of valve employed depends on nature of fluid flow control required operating pressure and temperatures as well as surround atmosphere. Solenoid valve and common pneumatic system symbols.

The meaning of the solenoid valve symbols is as below. When the inlet is blocked in the at rest condition as shown in figure 8 1 it is referred to as normally closed nc. Every box indicates one working position of the solenoid valve namely position. 3 2 way solenoid valves have two positions and three connection ports.

All of the valves represented above are 2 way inline valves that are used for flow control either on off or throttling.
