Cast Iron Safety Release Latches

Cast iron pressure release latches are durable, and provide good wear resistance. The material offers some resistance to corrosion, but it is not nearly as high as stainless steel, brass, or aluminum. Cast iron explosion venting latches are best suited for indoor processing applications, and those involving non-corrosive environments.
 
Some of the common uses for cast iron safety release latches include:
  • Powder Booths
  • Batch Ovens
  • Indoor Industrial Applications
  • HVAC Systems

Heavy-Duty Cast Iron Explosion Venting Latches

Brixon explosion venting latches are easy to operate and adjust and provide reliable primary or backup venting to other venting and pressure monitoring systems. All cast iron pressure release latches feature mild steel internals with an option of stainless-steel internals for corrosion resistance.
 
Our cast iron safety latches come in two finishes:
  • Powder Coat/Gray Painted Finish: A standard, economical finish that provides more corrosion resistance than paint but less protection than polished chrome.
  • Polished Chrome: Provides improved corrosion resistance and enhances the cosmetic appearance with a smooth, high-shine finish.
We also offer shims in different sizes with an option of steel, iron, or stainless-steel material.  Shim size options for each latch series are listed below.
