EMERGENCY RELIEF MANHOLE COVER

This kind of valves are installed on the roofs of the atmospheric tanks replacing manholes or access. The advantage of such emergency relief manholes is that fulfill a dual function, on one hand they allow a person access into the tank and otherwise evacuate the tank pressure in an emergency. Such valves must always be tared below the design pressure of the tank.

Emergency valves are designed according to API STD 2000, that determines the sizing of the valves to evacuate the vapours from the tank caused in case of fire.

Available in four constructions:

104STD in aluminium
104EEV body in carbon steel and inner parts in stainless steel
104VVV in stainless steel AISI 304L
104WWW in stainless steel AISI 316L

  • Sizes: 20" and 24" (other sizes on request)
  • Flange connections: API 650, DIN, ASA; or other standards and materials on request.
  • Set pressure: From +40 to 500 mm w.c.; or with a lever for set pressures over +2000 mm w.c.
