Overview
Midland Industries MPN 940173L is a 1/2 in. full-port brass ball valve with female NPT x female NPT (FPT x FPT) connections and a lockable quarter-turn handle. The forged-brass body uses a chrome-plated brass ball on PTFE seats and is rated to 600 psi WOG. The locking handle accepts a padlock so the valve can be secured in the open or closed position for lockout/tagout.
