ISD Instrument Regulator

Powering and protecting your pneumatic instruments just got easier thanks to the spring-loaded Welker I-Series Instrument Regulators. The ISD model reduces higher pressure filtered gas or air to a lower outlet pressure safe for your downstream instrumentation, helping prevent costly damage and interruptions to operation.

Multiple flow coefficients and pressure control ranges let you adapt the ISD to your instrument and application. The ISD Instrument Regulators are diaphragm-sensing for greater sensitivity, giving you more control when setting the outlet pressure. With a hex head adjustment screw, field adjustments are quick and easy. A locknut prevents the spring setting from changing due to vibration to help maintain a constant outlet pressure and flow.

Why make do with another regulator when you can customize a standard ISD? You have the power to choose the port layout that works best for your application and installation and arrange your accessories accordingly. The compact design and port configuration options allow the ISD to fit easily into a small enclosure or on a panel.

Diamonds are a service tech’s best friend. The easy-to-grip knurled spring housing on the ISD keeps hands from slipping during maintenance. Because no special tools are required, maintenance is uncomplicated and quick.
