Critical Service Advantages
High Precision
Inlet pressure matches reference pressure within 1-2% through wide range. Used in may test systems throughout many industries. See performance curves.
Computer Automation
Our sensitive dome-loaded design makes automating your process pressure easy and precise. See an example of automated pressure control.
High Pressure Service
Maximum pressure up to 5000 psig. Somewhat higher for custom applications. Learn details about our Instrument Series regulators.
High Temperature
Our stainless diaphragms can be used to 327C in many applications. Useful in petrochemical gas analysis and research (details).
Ultra Low Pressure Service
Using delicate diaphragms, our technology gives precision down to 0.02 psig (0.5 inWC). (details).
Aggressive Chemistry
Our many material options include 100% PTFE construction as well as Hastelloy C276 and SS316. Our products can be made compatible with virtually every aggressive chemical known. (details)
Ultra Low Flow Service
By far the lowest flow rate available, down below Flow Coefficient 1E-8 (<0.1 ml/min gas or 0.001 ml/min liquid). (details)
Low Dead Volume Service
Our 1/16" tube fitting option provides for total dead volume of 0.2 ml. Useful for High Performance Liquid Chromatography and gas analysis services. (details)
Two-Phase Flow
Our unique design allows for liquids and gases to flow together while maintaining incredible inlet pressure stability. (details)
