ZL Innovations Technology
External Magnetic Actuation Technology: Couples the torque or force required to actuate a valve across a hermetically sealed bonnet and has no continuous stem from inside to outside the valve, and hence doesn't contain a seal that can degrade or leak. This completes a magnetic circuit much akin to an electrical circuit.
ADVANTAGES OF ZERO LEAK MAGNETIC VALVES
No Rotating or Sliding Stem Seal at All
- Completely sealed bonnet enables truly zero emissions
- No maintenance or testing needed -- No repacking or periodic testing required
Only uses External Magnets: Our approach enables
- High-temperature operation including steam
- Welded or brazed on bonnet possible -- truly hermetic
- Welded, brazed, or soldered ports if desired
- Extremely cost-effective strategy
High Actuation Torques and Forces
- Never gets stuck -- asymmetric torque
- Works with all standard valves such as gate, globe, ball, butterfly, etc. of any size
- 6 sigma system reliability possible
