202F: Emergency Pressure Relief Vent
APPLICATION
The Treloar 202F emergency vents are used on above ground bulk plant and storage tanks. The emergency vent is an auxiliary to a free vent or pressure-vacuum vent. It acts to relieve excess internal pressure created by overheating, fire and over-pumping etc. These vents meet the requirements of API 2000 code as stipulated in AS 1940.
FEATURES
• Emergency vent comes in three emergency relief settings being 17.5kPa, 24kPa and 45kPa.
• Vents can be fitted to a 6” ASA 125 flange, however, we recommend the use of the 202SSF flange adaptor.
• The 202F vent, unlike other emergency vents, will show a failure mode, thus indicating that there are design or operational problems associated with the storage facility.
• The 202F on operating will completely open and remain open giving a maximum capacity of 15,850m3/hr at 17.5kPa. (The 202F has to be manually reset after operating).
• The body and lid are aluminium with the body having a P.T.F.E. bonded coating to prevent the lid sticking.
• The lid is anodised “red” for easy emergency observation.
