Safety Latches by Release Force

Safety latches are pressure release latches that provide venting to prevent the buildup of pressure that can result in an explosion. Once a specified amount of pressure accumulates, the latch pops open to instantly release the pressure. Often used in conjunction with other safety systems, Brixon Safety Latches are a reliable backup solution that work even when a loss of power causes other systems to fail. Release latches are used by a range of industries in applications where there is accumulation of dust, gas or mist including farm silos, HVAC systems, coal burning power plants, paint ovens, and more.

Adjustable Pressure Release Latches Designed for Performance and Reliability

Pressure release latches from Brixon feature an adjustable spring-loaded release that opens at a pre-set release point to prevent explosion or implosion by relieving pressure. In addition to pressure applications, our safety latches can also be used as a breakaway device or for security and product testing applications.
 
Our safety latches have a proven track record of product performance and are offered in different material options, including sparkproof options and finishes, to meet the requirements of your specific operating environment. Additional features of our latches include:
  • Manual mechanical operation
  • Adjustable latch release force to customize precise venting needs
  • Handles actuate the interior mechanism of larger models for manual opening
  • Custom linking
  • Choice of left or right handle configuration

Choosing a Latch Release Based on Pressure Requirements

Selecting the correct release force for your safety latch depends on a number of factors and should be determined by calculating pressure point of vessel release. Our calculator can help you choose the correct latch release for your application. Other determining factors in choosing a pressure release latch include:
  • Operating environment
  • Exposure to corrosive substances
  • Volatility of the pressurized substance
  • Material weight
  • Vessel construction.
 
Refer to the latest version of NFPA No.68 and all other applicable codes to calculate the venting requirements of your vessel: in general, the lowest practical setting should be used.

Factory Mutual Global (FMG) and National Fire Protection Association (NFPA) have different pressure setting requirements. To be safe, the lowest practical setting should generally be used. Always consult all codes and regulations pertaining to your specific situation. View our adjustments and latch selection technical data for additional information and calculations for choosing the correct latch release.
