GENERAL

1. The poppet is loaded by a spring in a normally open
    position as long as the system is balanced.
2. If the system becomes unbalanced and the    
    downstream pressure drops, the poppet moves
    towards the sealing area and prevents free,
    uncontrolled excess flow from the line.
3. If the downstream pressure increases, the ventilation
    outlet ("bleeding") enables the system to balance the
    pressures and (with the help of the spring) reset the
    system. In this situation, the poppet reverts back to
    Normally Open.


Excellent for Automatic Safety Shutoff in a wide range of areas:

• Fuel systems  • Toxic Media Systems  • Gas Systems  
• Valued Media Systems  • Hydraulic & Pneumatic
  Systems.
