Butterfly Valve MUELLER 65M

Construction

  • ANSI 125 Flange Design
  • One-piece stem

Performance Considerations

  • Seat selections will limit temperature range
  • Seat and body materials must be chosen carefully for compatibility with corrosive media applications.
  • Guidelines for throttling service:
    – Liquids -Line velocity should not exceed 20 ft/sec
    – Gases – Line velocity should not exceed 15,000 ft/min.

Typical Service

These soft-seated butterfly valves are designed for a variety of general applications in the control of water, steam, air, oil, gases, and corrosive media. They are equally effective for on-off, throttling, isolation, and dead end requirements. They are especially well suited for higher velocity service and vacuum service to 28″ Hg.

Features

  •  Dual durometer seat features a tough wear resistant elastomer bonded to a phenolic backup ring on 2″-14″ sizes and, aluminum back-up ring on 14″-36″.
  •  The soft elastic seat portion provides positive sealing – The backup ring provides strength for vacuum or high velocity services
  • The combination eliminates the need for flange gaskets • Stem seals include a primary seal between the disc hub and the seat hub, along with secondary O-ring seals at the top and bottom of the seat
  • This retains lubrication and prevents corrosion from outside elements. Stem is retained in the body for blowout proof design • ISO mount is standard • Double D shaft is standard for ease of actuation • Many material options available. See introductory pages of the Butterfly Valve section of the Mueller Steam Specialty Engineering binder for How to Order instructions and
    standard materials
  • A variety of operators can be supplied
    – Multi-position lever operator – Gear Operator – Pneumatic, hydraulic, or electric actuators with solenoids, limit switches,
    positioners and more, consult factory
