p&id

[fabio85]

hello to all I wanted to ask you how to represent on a p&id (like these http://ardnas20.files.wordpress.com/2011/05/pid-2.jpg) a 5-way solenoid valve http://www.pneumaxspa.com/module.asp?cod_mod=edtnot&cod_sot=56&cod_not=169) that I need to operate a hydraulic cylinder.
Thank you.

Hi.

 

[fabio85]

Can someone interpret what these symbols always mean by p&id?
Thank you.

pt in the circle is a pressure transmitter, local.
the dotted line to indicate a link to the picture (signal)
pah = high pressure alarm
pi = pressure indicator (hand gauge)
pr = a reset button (I believe)

ps: wouldn't you want to study these symbols a bit before improvising?

pr = a reset button (I believe)

if I interpret the symbolism well:
pah = pressure higt alarm = high pressure alarm
pr = pressure register = pressure recorder

on how to represent the 5-way valve on the pei you should know which equipment you have to control, usually I indic it for handling a two-way pneumatic valve with double effect.
Good evening.
