Electrically Actuated Ball Valve Symbol

An engineer may also include specific details below the control valve symbol.

Electrically actuated ball valve symbol. Type of valve employed depends on nature of fluid flow control required operating pressure and temperatures as well as surround atmosphere. Also known as actuated ball valves these have a motor that can handle high flow rates and pressures. Valves can be wired as normally closed unless actuated or normally open unless actuated. The spring pushes from the side that is drawn on and will return the valve back to its failsafe position.

P id symbols for control valve assembly and following actuators manual diaphragm spring type solenoid pilot motor electro hydraulic etc. Symbol for 2 port valve with two positions one position valve open with flow in both directions or valve closed with both ports blocked. They donâ t require a minimum pressure drop between the inlet and outlet for operation. Two ball valve with manual actuator.

As you increase the intensity of the electrical signal the motor opens the valve moving a ball with a v cut opening that proportionately allows more flow as the valve opens. Also known as proportional v ball valves these have a motor that adjusts and regulates flow in applications with higher flow rates and pressures than solenoid valves. Symbol for pressure inlet port of valve. The actuator is directly mounted to the valve.

Two way solenoid valve. These details may include the size function pressure rating and connection type of the valve. A piping and instrumentation diagram p id is a graphic representation of a process system that includes the piping vessels control valves instrumentation and other process components and equipment in the system. Many types of valves are required in a process plant for flow regulation or on off purpose.

Symbol for 3 port valve with 2 positions. Many types of valves are used in process piping and each has a different 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.
