Bronkhorst                   Pressure Controller


Bronkhorst Forward and Back Pressure Controllers are often applied in flow measurement or control applications to deliver a constant pressure inside a reactor chamber (from vacuum up to 400 bar), or to automatically adjust the process pressure according to the system requirements.

  • EL-Press - Proven performance in pressure measurement and control - Absolute, Gauge, or Differential

  • IN-Press - Industrial Style IP65 : Rugged & Weatherproof housing - Options for FM Class 1 Div 2 / ATEX Zone 2 Cat 3

  • IQ+Flow - Ultra-compact pressure meters / controllers - 1/2 the footprint size due to use of micro solid state technology (MEMS)

    Onyx Pinch Valves        

    Pressure Isolators

    Onyx Valve Company is a leading manufacturer of pinch valves, check valves, and pressure sensor rings. All of their products and materials are manufactured and assembled right here in America. With over 20 years of experience in the flow control industry, they pride themselves on the durability and longevity of their products.

    The Onyx Isolator Ring provides a simple method to measure pressure of slurries and corrosive fluids. The inside diameter of the Onyx isolator rings precisely match 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 with minimum down time.
