Pressure/Vacuum Diaphragm Valve deflagration- and endurance burning-proof (UB-SF)
a specialized pressure/vacuum diaphragm valve designed for maximum tank safety, providing protection against atmospheric deflagrations and endurance burning for explosion groups up to IIB3.
. It ensures superior tightness to minimize product loss and environmental pollution while protecting against overpressure and vacuum.
Deflagration/Endurance Burning Proof: Certified to withstand endurance burning (stabilized fire) and atmospheric deflagration, making it suitable for volatile products like styrene or acrylates.
High Tightness: The liquid-loaded diaphragm offers superior sealing close to the set pressure, reducing vapor emissions and complying with environmental regulations.
Safety Technology: Combines a dynamic flame arrester with a static unit for robust protection against flame propagation.
