ISPE

Where to Use

  • Upstream of sensitive pneumatic instruments as a standalone pressure control device or part of a conditioning system on air compressors, generators, and instrumentation panels

  • Upstream of sensitive pneumatic instruments as a standalone pressure control device used in the production, transportation, storage, and utilization of hydrogen (e.g., research institutes and laboratories)

Regulate ESG    

The ISPE model in Welker’s I-Series Instrument Regulators is a cost-effective, standalone piston-sensing instrument regulator suitable for regulating air and light gases, such as hydrogen.

With global and industrial decarbonization goals, the development and deployment of hydrogen and fuel cell technologies are growing in importance. Welker’s ISPE Instrument Regulator can be used across the hydrogen value chain to reduce the pressure of the hydrogen gas to a lower outlet pressure safe for the downstream equipment in your application, helping prevent costly damage and interruptions to operation.

Features

  • Piston-sensing
  • Compact, lightweight design
  • Multiple flow coefficients and pressure control ranges
  • Flexible port configuration

Benefits

  • Capable of regulating higher inlet pressures with minimal flow droop
  • Suitable for small enclosures and for portable and on-vehicle applications
  • Adaptable to pressure requirements of downstream equipment
  • Select accessory arrangement best suited for the installation and application
  • Uncomplicated maintenance requires no special tools and little downtime
