Emerson enhances Fisher GX control valve, for wider range of applications

The Fisher GX control valve and actuator system from Emerson Process Management is now available in constructions that meet the NACE MR0175/ISO15156 standards, making it suitable for the harsh applications typically found in upstream extraction facilities. In addition, electric actuators with facings meeting the ISO5210 standard can now be easily mounted. This extends the valve/actuators combinations available, enabling the device to be applied in particularly dirty environments and in remote locations with no compressed air supply.

“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.

The GX is available with Whisper Trim™ III low noise trim and an anti-cavitation trim, making the valve system suitable for severe service applications. Constructions that meet the NACE MR0103 standard, applicable to downstream refinery environments, are also available. The cryogenic version enables use down to -196°C 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.
