Ball Valve With Actuator Symbol
For example the note 2 300 rf pb indicates that the p id calls for this valve to be a 2 ansi 300 raised face piston balanced valve.
Ball valve with actuator symbol. Three symbols shown below are the gate valve symbols used in isometric drawings. Valve symbols typically describe the position number of ports and flow control method of particular valves. It is a modification of a generic valve symbol by inserting a vertical line between two triangles. The pipe lines are represented by lines connecting to each side of the valve symbol.
Many types of valves are required in a process plant for flow regulation or on off purpose. Here is a list of symbols for various types of valves used in process industry. This post shows industrial valve and actuator symbols found in different types of technical diagrams used to document instrument systems. Various types of lines are used to represent different pipes tubes and hoses.
Image above you can see the gate valve. Type of valve employed depends on nature of fluid flow control required operating pressure and temperatures as well as surround atmosphere. Valve symbols for p ids. Actuator symbols generally describe the motive force and control options.
These details may include the size function pressure rating and connection type of the valve. The generic symbol for a 2 way valve is two triangles pointing to each other with the tips of the inner points touching.
