PRESSURE/VACUUM RELIEF VALVES |
20th Century Technology & Design for Today's Environment
Introducing the TTI 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 this mean? Savings! Savings on product loss, savings on blanketing gas costs, savings on maintenance and rebuilding costs. With our bolt in Stainless steel seat design, valves can be serviced in position in many applications. It is faster to change out the seat than it is to remove the whole valve and take it in to the repair shop. This user friendly concept keeps your equipment operating efficiently and also reduces air pollution which benefits everyone. Shown below are a few products TORNADO™ TECHNOLOGIES INC. can supply for your application.

The TTI Relief
Valves are an end of
line or inline design that protects your storage tanks from over pressure or vacuum while filling,
emptying, expansion or contraction. The TTI valves relieve the over pressure gases into
the weather hood or pipe away lines from where it dissipates or is transferred
to a disposal process. The dead
weight design insures accuracy and repeatability of set points. Normal set points are 1/2
ounce. For set points above 1/2 ounce 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 our factory for assistance.

TANK VENTS THE COUNTER FORCE PRESSURE SUSPENDED VALVE ASSEMBLY |
|
The TORNADO™ TECHNOLOGIES INC. 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 ounce. Tornado Technologies has received independent verification of these leak rates. For more information, contact our factory. |
