port size of nordstrom plug valve, figure 4749
port size of nordstrom plug valve, figure 4749
(OP)
does anyone know the port size of a nordstrom figure 4749 (% of nominal pipe size)? I calculating flow through an existing valve and my value is barely too small when I use standard 40% assumption for plug valves. I'm thinking that the actual port size is larger, but I can't find it in any documentation have.
