Abstract
A ball valve employing a flush inlet in the ball and a flush exhaust port in the valve body for communication with the ball valve port when the ball is oriented to allow source fluid to enter the ball valve port through the flush inlet is disclosed. The ball valve allows for convenient back flushing of an optional filter or located in the ball valve port and subsequent expulsion of debris flushed from the optional filter from the valve body through the flush exhaust port. The disclosed ball valve also allows for a simple method of collected fluid samples when a sample collector is connected to the flush exhaust port. The disclosed valve also operates to completely arrest fluid flow from the first end of the valve body to the second end in a manner similar to valve known in the prior art.
