Key Features

  • Made from brass for higher corrosion resistance than steel
  • Zinc-plated steel lever handle for manual on/off control
  • Full port flow for higher operating efficiency than standard port
  • Pounds per square inch (psi) rating of 600 for water, oil, and gas (WOG) and 150 for steam working pressure (SWP)
  • Female National Pipe Taper (NPT) threads for use with male threaded pipes

Product Description

The Milwaukee BA-475B two-piece full port ball valve is made of brass and has a lever handle and female National Pipe Taper (NPT) threaded connections on both ends. This valve is made of brass for higher corrosion resistance than steel and has a lever handle made of zinc-plated steel for manual on/off control. The ball valve is full port for reduced friction; its inner diameter is the same as the inner diameter of the pipe it connects to enable maximum operating efficiency. The maximum pressure is 600 pounds per square inch (psi) for use with water, oil, and gas (WOG) and 150 psi for steam working pressure (SWP). The working temperature range is 0 to 350 degrees Fahrenheit. The valve is inline for connecting two pipes going in the same direction and has NPT threads on both ends for creating tighter seals than straight threads. Polytetrafluoroethylene (PTFE) seats and seals reduce the risk of valve leakage. This valve is for use with water lines, processing plants, and agricultural applications and meets standards MSS SP-110, ANSI/NSF 61, and ASME A112.4.14 for quality assurance.

Ball valves use a spherical disc to control the flow between pipes, tubes, or hoses. Flow is allowed when the hole that pierces the ball-shaped disc is in line with the inlet and outlet of the valve. Flow is blocked when the ball is horizontally swiveled 90 degrees, so that the hole of the ball is perpendicular to the opening of the valve. Ball valves can be referred to as full port or reduced port (also known as regular or standard port) depending on the inner diameter of the valve. A ball valve is full port if the hole of the ball is the same size as the inner diameter of the connecting pipeline (resulting in lower friction) and is reduced port if the hole of the valve is one pipe size smaller than the pipe, resulting in less flow through the valve than through the shaft of the pipe. Ball valves may have a handle or lever that aligns with the ball’s position (open or closed) for manual operation. They are primarily used in air, gas, liquid, and steam applications.

The Milwaukee Valve Company manufactures manual and actuated valves, controls, and control accessories. The company, founded in 1901, and headquartered in New Berlin, WI, meets International Organization for Standardization (ISO) 9001:2008 and 14001:2004 standards.
