smartvent pressure relief vent
LINDEN, NJ, September 9, 2011— Girard Equipment, USA has been awarded a US patent on a new style of Pressure Relief Vents for Intermediate Bulk Containers (IBCs).
The “Smart Vent” is a self-acting, spring-loaded device that threads into a standard 2” female port. Pressure settings are set at the factory to operate at 5 PSI (.34 bar) but also can be custom ordered with a variety of settings. Vacuum settings are set at 1” Hg (.03 bar) and can also be adjusted in the field.
Each Smart Vent has a “Quick Venting Release” (QVR) feature built into its design. The operator can simply press down on the top cover to manually relieve internal pressure. This feature has proven to be most beneficial to operators who may experience difficulties when trying to open IBCʼs with built up pressures or vacuum within the tank. A machine ring groove allows the vent to be tethered directly to the IBC. Available in both 2” BSP and NPT male connections, the design can also be customized with a 2″ tri-clamp adaptor connection used for venting applications in food grade applications.
Some other unique features making the Smart VentTM so smart are:

  • All cast and precision machined stainless steel • Low profile design
  • “Quick Venting Release” (QVR) feature
  • PTFE Encapsulated O-Ring Seals
  • Electropolished surfaces for easy cleaning
  • Vent can be hermetically sealed to guard against unauthorized access
  • Rugged and durable
  • Compact and easy to install
