Racking arm

A racking arm for use with a holding tank having a wall defining an interior area of the holding tank, said racking arm comprising:

• an elongated barrel arm having a distal end structured and arranged to be placed through the wall into the interior area of the holding tank, a proximal end to be positioned outside the holding tank and a barrel arm opening at or near said distal end of said elongated barrel arm;
• and
• a control valve having a tubular valve body, a tubular barrel rotatably disposed in said valve body, a handle attached to said tubular barrel, a bearing, an O-ring and a pin, said valve body having a first end, a second end, a bearing groove in an inner surface of said valve body, an O-ring groove in said inner surface of said valve body, an elongated slot through said valve body and a pin aperture through said valve body, said bearing groove retaining said bearing, said O-ring groove retaining said O-ring, said tubular barrel having a barrel body rotatably positioned inside said valve body with each of said bearing and said O-ring being disposed between said valve body and said barrel body to sealably allow rotation of said tubular barrel in said valve body, said barrel body defining a first end and a second end of said tubular barrel, said barrel body defining a flow channel between said first end and said second end of said tubular barrel in fluid flow communication with said barrel arm opening, said barrel body having a locating groove in alignment with said pin aperture, said handle disposed through said slot so as to rotate said tubular barrel inside said valve body upon movement of said handle along said slot between a first end and a second end thereof, said pin received through said pin aperture into said locating groove to position said tubular barrel in said valve body, said proximal end of said elongated barrel arm integral with or attached to said first end of said tubular barrel such that rotation of said tubular barrel by said handle will rotate said distal end of said elongated barrel arm so as to selectively position said barrel arm opening in the interior area of the holding tank.
