Fisher GX Globe Control Valve and Actuator System – Sliding Stem Valves
Fisher GX Globe Control Valve and Actuator System – Sliding Stem Valves
Fisher GX globe control valve and actuator system is part of the sliding stem valve range that is designed to control a wide range of process liquids, gases and vapours. The Fisher GX is compact, rugged and reliable in design and simple to select.
The actuator selection of the Fisher GX sliding stem valve is automatic once the valve body construction is selected. The optimised design results in reduced complexity and parts count which keeps maintenance costs low.
The GX globe control valve meets the requirements of both EN and ASME standards. It is available with a complete accessory package, including the Fisher FIELDVUE DVC2000 and FIELDVUE DVC6200 integrated digital valve controllers.
