Pressure Measurement Gauges

The Magnehelic® gauge is used to measure the differential pressure between the "clean" gas side and the "dirty" gas side of the baghouse. The Photohelic® gauge is a Magnehelic gauge with the capability to allow a collector to clean-on-demand. Photohelic and Magnehelic gauges can be visually checked anytime to monitor system problems.

Surge Valve

The Surge Valve is a three-way valve, which allows fast and easy cleanout of Magnehelic and Photohelic lines without disconnecting the lines to manually clean. The ball valve is designed to protect the gauges from breaking under high pressure cleaning.

Surge Valve features and benefits

  • Simple to operate-close the valve and a push of a button cleans the entire line in seconds
  • Can connect to a timer for automatic cleaning
  • Withstands temperature ranges from 32° F (0° C) to 200° F (93° C)
  • Heavy duty construction - suitable for service up to 150 psig pressure
