Advantages

The National Science Foundation has recognized the potential of Big Horn Valve's technology for pollution prevention. The research agency has funded BHVI, Moog, Inc. and Florida State University to develop a magnetically coupled, pneumatically operated, emission-free valve for moderate pressure and temperature service. The valve is targeted for use in refineries, petrochemical plants and other environmentally sensitive applications. Key to this design, a permanent magnet coupling enables actuation across the valve housing, which serves as a positive barrier to external leakage. High-strength magnets and low rotational friction combine to provide a four-to-one torque safety factor.

The High-Pressure, High Torque MagBall™ Valve has a body that can withstand 2500 psi. and in the 2 inch size is capable of providing torques up to 5000 inch-lbs. to open and close the valve under the harshest conditions. This torque capability is equal to or greater than any stemmed valve.

Big Horn Valve's unique StemLess” magnetic ball valve technology offers major advancements over traditional ball valve technology.

These valve technology advances provide the end user with the following capabilities:

  • Magnetic actuation systems:
  • Provides uniform levitation valve actuation…Smooth even low turning torque.
  • Fail Safe magnetic interlock- no valve stem breakage
  • Improved safety.
  • 1/4Qtr. on/off actuation standard- Standard ball valve…User friendly.
  • Standard ball is encased in a 360° rotational cartridge- even seal pressure…Longer seal life.
  •  “StemLess” valve technology:
  • Assures “Zero” fugitive emission discharge for the life of the valve…Safety and inspection improvements.
  • Low turning torque at higher pressures…Allows smaller (less costly) actuators and positioners.
  • Eliminates conventional valve stem “sniffing” inspection requirements… Less costs
  • Standard Ball valve components:
  • MagBall balls are modified standard balls with wide material and trims available… User friendly
  • MagBall seals are standard ball valve seals… User friendly.
  • Standard ANSI flange to flange dimensions for all sizes.
  • Standard 150lb or 300lb flanges…User friendly.
  • Standard ball valve flow capacity (standard or full port) capabilities…eliminates flow changes
  • Standard ¼ turn actuation for all MagBall valves- user friendly.

Over the past eight years, Big Horn Valve, Inc. (BHVI) has developed the a zero-emission, axially rotated valve that offers high flow efficiency, a small valve envelope and no-leak path between the fluid/gas and the environment. BHVI has developed and tested prototype valves for water, petrochemical and cryogenic applications. These valve designs center around innovative patented and patent pending technology.

KEY FEATURES:

  • a small axial envelope
  • low actuation torque
  • minimal flow energy loss
  • low piece count
  • linear valve characteristic
    With its half-turn rotation, our Stemless valve can be actuated manually, pneumatically, or electromechanically.
