 Introducing the TFS Series 2000 Pressure/Vacuum Relief
Valve - a truly unique product for vapor control. The heart of this product is a unique seal called the counter force, pressure suspended valve sealing assembly. This
sealing assembly affords the lowest leak rate in the industry while also improving set point crispness and
accuracy, also extending the life expectancy due to the air cushioned ride of the Counter Force Pressure Suspended Valve Assembly. What does all this mean?
Savings! Savings on product loss, savings on blanketing gas costs, savings on maintenance and rebuilding costs due to the easily replaceable seats on scheduled
maintenance programs, and also a reduction in air pollution due to superior sealing system that we all benefit from now - and in the future
 The Series 2000 is an end of line design that protects your
storage tanks from over pressure or vacuum while filling, emptying, expansion, or contraction. The Series 2000
relieves the over pressure gases into the weather hood or pipe away lines from where it dissipates or is transferred. The dead weight design
insures accuracy and repeatability of set points. Normal set points 1/2 oz. For set
points above 1/2 oz. to 2 PSI, please consult factory. Before ordering, please review ordering data sheet to ensure that you receive the required product. For your
application, or general information, contact Advanced Rupture Disk Technology for assistance.
 The Tornado™ Technologies Counter Force Pressure
Suspended Pallet Assembly has proven to set new standards in high percentage of set point leak rate. We have achieved what we believe is the best achievable low
leak rate for a deadweight valve. Using a 6” mid-sized valve complete with the Counter Force Pressure Suspended Pallet set at .525 oz./pressure, 98% of set
point required a .3 scfh of flow to maintain 98% of .525 oz. Tornado™ has received independent verification of these leak rates.
