Mueller Industries AU17864 7/8" 3 Way Ball Valve

Mueller Industries AU17864 is a 7/8" 3-way ball valve designed for various plumbing and industrial applications involving fluid control. It offers reliable performance and versatile flow management with its three ports and single-ball element. Mueller Industries AU17864 7/8" 3 way ball valve allows you to control the flow of liquids or gases in three directions, opening or closing specific ports as needed. Also, it provides a shut-off point for isolating specific sections of a system for maintenance or repairs. Enables mixing or diverting fluid streams from different sources to a single outlet. It helps balance pressure in different parts of a system by directing flow accordingly.

Key features:

  • Weight: 1.67lbs/757.5g. 
  • Durable construction: Built with high-quality materials like brass or stainless steel for long-lasting performance and corrosion resistance.
  • Leak-proof design: Tightly sealed ball valve mechanism minimizes the risk of leaks, ensuring reliable operation.
  • Easy operation: Lever handle or knob provides quick and convenient control of the three ports.
  • Full port design: Offers minimal flow restriction for efficient fluid movement.
  • Wide range of applications: Suitable for various liquids and gases, including water, steam, oil, air, and some chemicals depending on the specific model and material.

Signs of a Faulty Mueller Industries AU17864 3 Way Ball Valve

Here are the signs of a faulty 3 way ball valve:

  • Leaking: Visible leaks around the valve stem, packing, or connections indicate compromised sealing.
  • Reduced flow: Lower than expected flow rates in any of the ports could be due to partial clogging, internal damage, or malfunction.
  • Inconsistent flow: Fluctuating or pulsating flow might point to worn-out components or internal issues.
  • Unintended flow: Fluid flowing through the wrong port or ports unexpectedly suggests internal malfunction or incorrect valve operation.
  • Difficult operation: Valve handle feels stiff or requires excessive force to operate, indicating binding or internal friction.
  • Unusual noises: Grinding, screeching, or buzzing sounds coming from the valve suggest internal wear or malfunction.
  • Visible damage: Cracks, corrosion, or physical deformities on the valve body, handle, or connections raise concerns about compromised functionality.
  • Mixing issues: Improper mixing of hot and cold water, or incomplete diversion of fluids between ports, could indicate internal issues affecting flow direction.
  • Pressure imbalances: Pressure fluctuations or differences between ports might point to malfunction affecting pressure balancing capabilities.
  • Increased energy consumption: Malfunctioning valves might draw more power due to internal issues.
