	Worldwide Headquarters – Marshalltown Iowa Marshalltown application and design engineers along with the field sales organization support customers with their tough applications day in and day out.
	Research & Engineering Lab Emerson's Fisher R&E capabilities extend worldwide with engineers and labs in the North America, Europe and Asia. Emerson has the technical expertise around the world to provide our customers the products and support they require to be competitive in today’s business environment. Our technologists are active in publishing technical articles and in the development of national and international industry standards.
	Cycle Life Lab Verifying product life meets expectations Fisher products are subjected to humidity and temperature extremes in environmental chambers to verify their reliable operation. Emerson develops and tests valve packing systems with exceptional cycle life that allow our customers to meet and exceed EPA regulations for fugitive emissions of volatile organic compounds. We cycle test bearings and seals at elevated temperatures in a hot air system to ensure their performance and reliability. Our proven composite rotary valve bearings and seals are patented technologies.
	Vibration Lab Ensuring performance in extreme conditions Using two electrodynamic vibration systems we measure the ability of a product to withstand vibration extremes. Shaker tables produce 1,500 (6,672 newtons) and 4,500 pounds (20,017 newtons) of force.
	Experimental Stress Lab Safety and code compliance Experimental stress analysis and finite element analysis make certain the pressure boundaries for Fisher products are within accepted factors of safety.
	Cryogenic Testing Lab Testing at actual service temperatures Control valves intended for cryogenic service undergo extensive testing for proof of operability and tight shutoff capability. The cryogenic valve area allows the cold testing of valves in any of four cryogenic test tanks and includes a dedicated 6,000 gallon (27,276 liter) liquid nitrogen supply tank, digital temperature measurement equipment and a mass spectrometer for leakage detection.
	Dynamic Performance Labs Testing products the way customers use them We use open- and closed-loop dynamic analyses in determining how a control valve assembly will perform when in service. Our investment in five operating dynamic performance loops around the world is unequaled. We use these loops to improve Fisher product designs and compare them to other offerings. We demonstrate our diagnostic capabilities in a dynamic flow loop environment in person or remotely wherever you have internet access. You can participate in a performance evaluation on-line by causing a valve or instrument malfunction in the dynamic performance loop, and then allowing FIELDVUE® Instrumentation to detect, diagnose and recommend corrective action. We call this capability Performance Diagnostics (PD), an industry first.
	Education Center We continue to provide training to both sales representatives and customers worldwide.
