Quality Gauge And Valve Series QRW & QTW

The Quality Series QRW-20 and QTW-20 are designed so that they can be welded directly on to a pressure vessel. Weld pad gauges are used where regular gauges and valve construction in impractical, due to space constraints, solid matter in the suspension and thermal stresses on the gauge glass from the associated piping. Included are applications involving high vibration, highly viscous liquids or liquids with considerable amounts of solids.

Quality Weld Pad Gauges are available in both reflex and transparent applications. These gauges are designed to take pressure within the gauge itself. These gauges are not designed to replace the tank strength lost due to slotting the pressure vessel. It is therefore impossible to give a pressure rating to the weld pad gauge.

• Flat glass liquid level gages designed to become an integral part of the vessel.
• For direct mounting to vessel wall.
