43Lbs. - 180 Lbs. Safety Release Latches

Safety latches are used to release pressure at a specific level to mitigate explosions and other workplace hazards. They can be used on the interior or exterior of a vessel, in vacuum applications, and can be combined for use on doors, vent panels or other large surfaces. Release latches are typically used in conjunction with alarm system and operate manually without the use of electricity.

Understanding Pressure Requirements for Selecting a Safety Latch

National Fire Protection Association (NFPA) and Factory Mutual Global (FMG) have specific maximum pressure requirements for safety latch applications. NFPA 68 Standard on Explosion Protection by Deflagration Venting is a great starting point. Always refer to all applicable codes, and regulations pertaining to your specific situation and municipality. In general, you should always choose the lowest practical setting to ensure safety and effective pressure control. It is important to adhere to the appropriate guidelines not only for workplace safety, but to ensure compliance under their industry standards.

Other considerations for choosing a safety latch include:
  • Material weight of the safety latch
  • Vessel construction.
  • Resistance to heat, corrosion, or sparking
  • Operating environment where the latch will be installed
  • Substance volatility for the intended application
