ABSTRACT:
A ball valve is described having a latching handle with a latch plate having raised lugs that engage the handle, a latch mechanism or both to act as detent stops in predetermined rotational positions. A flat spring rolled at one end urges the latch mechanism into the latched position and a pivoting cap secured to the handle is latched by simultaneous action of the latch mechanism to block access to a nut securing the handle assembly. Provision is made for attaching a padlock.
