ISPE Instrument Regulator

Brand: Welker, Inc
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.

Sense & Sensibility

Multiple flow coefficients and pressure control ranges let you adapt the ISPE to your instrument and application. The ISPE Instrument Regulators are piston-sensing, allowing for a quicker response to pressure adjustments.

Set It And Forget It

A square head adjustment screw allows you to quickly and easily set the outlet pressure. With a locknut to prevent the spring setting from changing due to vibration, you can set the ISPE once and be sure the outlet pressure will remain constant.

On the Weigh Down

The ISPE’s small size, lightweight construction, and flexible port configuration allow it to easily fit into small enclosures and in portable and on-vehicle applications. The ISPE’s small size, lightweight construction, and flexible port configuration allow it to easily fit into small enclosures and in portable and on-vehicle applications.
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
