How to determine the gas consumption of a pneumatic control valve?
Thread Content
I would like to ask everyone: how is the air consumption for pneumatic control valves determined, and what is the calculation formula?
It should be stated on the valve instructions; you can find out by checking them
To determine the air consumption of a valve, it is first necessary to identify the model of its actuator; once the actuator has been selected, the valve’s air consumption can be determined.
The technical parameters of valve positioners include air consumption.
SH 3020-2001 Code for Design of Gas Supply for Petrochemical Instruments http://bbs.hcbbs.com/viewthread.php?tid=5159&highlight=3020 HG/T 20510-2000 Regulations for the Design of Instrument Gas Supply http://bbs.hcbbs.com/viewthread.php?tid=104631&highlight=20510 These two codes are basically consistent regarding the estimation of the gas consumption of pneumatic actuators and the total gas supply capacity. Download it and take a look.
:victory: Thank you~~~
