Pressure Sensor RingsOnyx Pressure Ring pic

The Onyx Isolator Ring provides a simple, accurate method to measure pressure of slurries and corrosive fluids. The PSW series is compatible with flanged pipe connections. Nesting inside the bolt circle of mating flanges provides accurate alignment and minimum weight at the lowest installed cost.

 The inside diameter of the PSW precisely matches standard pipe for smooth, unobstructed flow, self-cleaning operation, and minimum turbulence and friction. Onyx ultra-deep vacuum filling insures the highest accuracy in the industry. The patented “Module Seal” – standard on all Onyx Isolator Rings – allows instruments to be or replaced or calibrated without interrupting the process.

Ideally designed to handle all types of slurry services, Onyx features both drop tight on-off and modulating duty pinch valves. Onyx pinch valves are easily maintained. Each valve is designed with an easily interchangeable sleeve, which is the only valve part that comes in contact with the process fluid. The design configurations for the Onyx Pinch valve are virtually unlimited, with the changes in enclosure, pinching mechanism, sleeve type, and actuation the possibilities are endless.

The Onyx Duckbill Check Valve is reliable and cost effective flow control solution. These products are 100% rubber heat molded products that are suitable for almost any environment. These products are maintenance free and have no mechanical components. Their revolutionary design eliminates the need for an outside energy source, will not warp, freeze, or clog. Their virtually silent functionality make them great for any application.

 

Onyx Wafer Check picWafer Check Valves

The WCV Check valve operates solely on line pressure and back pressure to open and close, no outside energy source is required. As line pressure builds, the elastomeric flapper disc is pushed away, allowing the water to pass. The memory of the rubber will cause the flapper disc to return flat, and back pressure will seal the flapper against the plate to prevent backflow. The WCV Check valve is designed to be inserted between two mating flanges.
