Level Transmitter Isolation Valve

SKU Isolation valve

The indu-tech level transmitter isolation valve has an optimised design that enables superior level measurements, simplified installation and the industry’s only Swirl-Purge™ in-situ flushing feature, the Indu-Tech Level Transmitter Isolation Valve sets the standard for long-term and trouble-free performance:

  • Bubble tight shut-off (Isolation and Safety)
  • Custom flange bolt configuration that accommodates both tank nozzle and Transmitter bolt patterns
  • Permits removal of the Transmitter if required
  • Equipped with purge ports on instrument and process sides of valve thus allowing cleaning of the nozzle and instrument
  • Full ANSI rated , 150,300, 600 PSI rated
  • Metallurgies to suit the process application (Titanium, Hastelloy, Stainless Steels)
  • Wafer Ball Valve with “Blow-out proof” Stem

Learn How the Indu-Tech Isolation Valve Works


Tank Side Swirl-Purge™

The Swirl-Purge in-situ flushing feature maintains a clean passageway between the level transmitter and the tank ensuring optimum level transmitter readings during normal operations. It continues to perform effectively under tough applications, including black & white liquors, acids, peroxides, slurries and other process mediums.

Instrument Side Swirl-Purge™

The ¼-inch port instrument side purge performs several functions. The port provides instrument side pressure relief and it can be piped to provide pressure relief for applications such as hydrogen peroxide service. The instrument side purge can also be used for level transmitter calibration without the removal of the level transmitter, allowing the instrument technician to calibrate each level transmitter without removing it from the tank. Closing the isolation valve (bubble tight) allows the technician to pump metered air into the instrument side cavity and calibrate the instrument. Another function of the level transmitter side purge is to keep the diaphragm environment clean and free of contaminants to help ensure consistent and accurate readings.
