Core Technical Advantages
-
Precision Control at Low Pressures: Specifically engineered for low-pressure service, the T208VR uses an oversized diaphragm to provide high sensitivity. This allows it to maintain a stable vacuum setpoint even when the vacuum source (the pump) fluctuates.
-
Tamper-Resistant Security: The adjustment screw is protected by a dedicated cap. This prevents accidental changes or unauthorized tampering with the vacuum setpoint—a critical safety feature when protecting delicate, thin-walled storage tanks.
-
Maintenance Standardization: The T208VR shares a high percentage of internal components—such as springs, orifices, and diaphragms—with other members of the T208 series. This reduces spare parts inventory and simplifies maintenance training.
-
Material Flexibility: To handle aggressive chemical vapors or coastal environments, the regulator is available in multiple materials, including stainless steel for superior corrosion resistance.

Applications and Industry Sectors
The T208VR is the gatekeeper for vacuum systems where precise regulation is more important than simple relief.
-
Tank Blanketing Systems: Working alongside a blanketing regulator (like the T205B) to manage the recovery of expensive or hazardous pad gases during filling/emptying cycles.
-
Chemical Processing: Controlling vacuum levels in distillation columns or reactors where specific pressure boundaries are required for chemical reactions.
-
Pharmaceuticals: Maintaining sterile vacuum environments in storage vessels or transport lines.
-
Food and Beverage: Used in processing lines where a precise vacuum is needed for deaeration or product transfer without collapsing the container.
