    Pressure on WOG rating

    Thanks for all your response. So there is no equivalent between WOG rating and ANSI Class rating. So if the maximum working pressure is 3000# WOG, what pressure for the ball valve should I choose? Thanks.

    Pressure on WOG rating

    Hello, All, Anyone know if a 1" ball valve with pressure in 3000# WOG rating means the same as 1" ball valve in ANSI Class3000LB? What is the different between WOG rating and ANSI Class rating? Thanks.
