As emergency venting devices for installation on storage tanks with a VRV to protect against hazardous excess pressure but minimize the loss of gas/vapours. Also suitable as replacement of a manhole. It does not protect against the hazard of explosion or stabilized burning.
Emergency Relief Valve is a highly developed emergency pressure relief valve with high flow capacity. It is primarily used as a safety device for emergency pressure relief for storage tanks, containers, silos, and process engineering equipment; it offers reliable protection against overpressure and prevents impermissible product vapour loss close to the set pressure.
