Hi All,
Please could you assist me in clearing up a sizing query...
I have a PSV on an air receiver:
Set pressure: 19 barg
Orifice: 0.212''²
Operating temperature: 70°F
I am not sure if this valve is the original that came with the equipment or has been changed out for something that just fit (before the time I came here).
I have used the Emerson PRV² SIZE software and it says I can use an Anderson Greenwood 81P with a -4 (0.049''²) orifice.
I'm getting a little confused, can you please help me.
Thanks
Bev
