Onyx Valve’s pressure isolator rings are a simple, cost-effective way to measure pressure or level on sewerage, sludge and slurries. They come available with flanged, screw-on and Tri-Clover connections. A patented “module-seal” enables instrument change-out or calibration without removing the ring from the process pipe. Any combination up to three gauges, switches or transmitters can be mounted per ring.
