Advantages:

• Small, inexpensive pressure relief fuse
• One moving part
  
• Compact, accurate relief device
  
• Set point accuracy +/- 5%
  
• Available in 316 stainless steel
  
• Viton "O" rings are standard
  
• Bubble-tight to set point
  
• Bonnet "O" ring prevents contaminants from entering the valve
  
• On opening, the bonnet "O" ring is forced down to give a visual indication that the pin has buckled and pressure has relieved

• The precise pin acting as the set point sensor & actuator obeys Euler's Law
• The pin cannot fatigue

Application: Relief for high pressure non-toxic cylinder gas
