Is a 600 wog and 150 wsp good for 600 psi water pressure?
Technically yes, but any fluctuation above 600 may cause
failure.. 600 PSI of water is A Lot of pressure I would recommend a
valve with a 1200 wog and 300 wsp rating.. ask for a 300 lb ball
valve at any supply house and they will know what you are talking
about.. it is a much more expensive and withstands much more
abuse.
