Emerson has added several new capabilities for the Fisher® GX control valve and actuator system range which make it suitable for a wider range of applications. These include the addition of a Whisper Trim™ III low noise trim and an anti cavitation trim, making the valve system suitable for severe service applications. There is also a cryogenic version which enables use down to -196C and a design specifically for use in pressure swing adsorption (PSA) skids. To verify cycle life, the PSA design has been successfully tested to withstand over 1 million high speed cycles. The GX is a compact and rugged globe-style valve system that can control a wide range of process liquids, gasses and vapours. Operations and maintenance savings are delivered through the use of standardised constructions and the predictive diagnostics and performance advantage of the integrally mounted Fisher Fieldvue DVC2000 digital valve controller. Even the cryogenic and PSA designs use mainly standard parts, enabling shorter delivery times.
