Key Benefits and Advantages

  • Flow-Optimized Disks: The internal geometry is engineered to provide more flow than comparable models, ensuring your application receives the necessary volume without increasing the physical footprint of the regulator.

  • Comprehensive Overpressure Protection: Offers one of the largest selections of protection options in the industry, including internal relief, high-pressure/low-pressure slam-shut, and secondary seats to meet strict safety mandates.

  • Exceptional Versatility: With a wide variety of body sizes, end connections, and orifice options, the CS800 can be tailored to almost any commercial installation requirement.

  • Material Flexibility: Bodies are available in gray cast iron, ductile iron, and steel to accommodate different regional standards and environmental conditions.

  • Hydrogen Ready: In support of the energy transition, standard CS800 units are ready for up to a 25% hydrogen blend by volume, with 100% hydrogen versions available upon request.

  • Precision Billing Accuracy: Features Fixed Factor and Pressure Factor Measurement (PFM) accuracy capabilities, ensuring consistent pressure for downstream metering and high-efficiency gas appliances.

  • Maintenance Simplicity: Designed with the field technician in mind, only standard tools are required for pressure adjustments or orifice removal, significantly reducing service time.

Technical Properties

  • Operation: Direct-operated and spring-loaded for fast, reliable response to load changes.

  • Pressure Registration: Offers options for both internal and external pressure registration depending on the specific application and sensing requirements.

  • Body Sizes: Covers a broad range of standard commercial pipe diameters.

  • End Connections: Available in threaded (NPT/ISO) and flanged configurations.

  • High Reliability: Built with few moving parts to minimize mechanical wear and extend intervals between scheduled inspections.

Field of Application

The CS800 Series is the preferred regulator for medium-to-large commercial gas meter sets and light industrial process lines. Its ability to handle high flow rates makes it ideal for facilities with large, variable gas loads.

Primary Industries and Uses:
  • Commercial Buildings: Gas supply for shopping centers, schools, and large office complexes.

  • Light Industrial: Direct pressure reduction for boilers, industrial furnaces, and heaters.

  • Municipal Distribution: Use in district regulating stations and commercial-scale meter sets.

  • Future Energy Systems: Transitioning networks utilizing hydrogen blends or 100% hydrogen fuel.
