SMA Valve

Revolutionary Thermal Valve Design

At Unison, a wholly owned GE subsidiary, SMA valves have a long life, high reliability, and fast actuation time. Our valve design features exclusive shape memory alloy which allows for a significant reduction in actuation time, up to 85% compared to other mechanical thermal valve designs. Unison’s SMA valves have 3 components compared to 12 in a typical design, thus creating higher reliability. This simplistic design is both pressure and thermally actuated ensuring a long life. The SMA Valve can be sized to meet the required performance in either an open assembly or self-contained cartridge design.

Benefits over Traditional Designs:

  • Low Complexity
  • Fast Thermal Actuation (15 seconds)
  • Long Thermal Life (~200,000 cycles)
  • All metal design
