Emerson enhances Fisher® GX Control Valve Range
Severe service trim capabilities, cryogenic construction and a PSA version added to the general purpose valve range.
Emerson announces 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 -196ºC 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 valve system has been particularly well received by our customers, and these new options make it even more versatile,” said Praf Patel, Emerson’s European Business Unit Manager for sliding stem valves.
“In particular, our customers have said they value the high performance of the overall package – which includes the valve, the actuator and the digital positioner – because of its positive impact on loop and plant performance.”
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, which are both arduous applications, use mainly standard parts. This enables industry-leading delivery times for these valves of just three weeks ex works. Valves with a range of standard options are available in one week.
