Emergency Relief Vent Is Available In Top-Guided And Hinged Configurations
A new line of manway pressure and pressure/vacuum relief vents from Valve Concepts, Inc. (
“The unique design also permits the pressure pallet assembly to be easily removed for unobstructed access to the tank for cleaning, inspection or repairs,” says Aaron Brantley, product engineer for Valve Concepts, Inc. “Plus, the flange base incorporates a set of integrated lifting lugs for easier removal or installation of the entire unit.”
Unlike competitive emergency pressure relief vents that use an O-ring for sealing, 8900 Series units utilize a flat diaphragm, which has a thickness based on the vent size and customer-specified set point. As a result, it forms around the seat to provide a tighter seal and improved reliability.
