Pressure/Vacuum Valves and Flame arresters
Maintain a constant vacuum by limiting the vacuum source or controlling the vacuum with positive pressure.
We offer a wide variety of flame and detonation arrester products with maximum flow to pressure drop characteristics. Our portfolio includes in-line, free vent, deflagration and detonation flame arresters. Enardo™ flame arresters use spiral wound, crimped-metal ribbon flame cell elements to inhibit flame propagation by absorbing and dissipating heat. Connection sizes range from 3/4 inch up to 36 inches.
Pressure/Vacuum relief valves are installed on storage tanks to control evaporation and emission losses resulting from hazardous vapor-producing products. Emergency relief vents provides emergency pressure relief for storage tanks when exposed to over pressures not handled by standard tank vents.
