Important considerations when choosing a safety latch include:

• Material weight
• Operating environment
• Resistance to extreme temperatures or corrosion
• Substance volatility
• Vessel construction

Our Latch Identifier can help you determine the best safety latch for your pressure release application. Simply select your desired specifications and our calculator will determine your best explosion venting latches!
National Fire Protection Association (NFPA) and Factory Mutual Global (FMG) each have different pressure setting requirements that you must adhere to for safety compliance. NFPA 68 Standard on Explosion Protection by Deflagration Venting is a great starting point. Always refer to all applicable codes and regulations about your specific situation and municipality. As a general rule, you should always choose the lowest practical setting to ensure safety and effective pressure control.
