The GEMÜ 566 stainless steel globe valve has a valve body in which the control mechanism is already integrated. In addition to a pneumatic actuator, there is also a manually operated version and a motorized version.
By integrating the control mechanism into the valve body, it is possible to subsequently switch from a manual actuation type to an automated actuation type at any time. The particular advantage of this is that the components involved are located outside the medium-wetted area. This means that from the start, the plant operator enjoys a very high degree of flexibility with regard to potential changes to their operational processes.
The medium-wetted part is separated from the control mechanism by an additional separating diaphragm. The diaphragm is available in EPDM or FPM materials. The investment casting, stainless steel valve body has a threaded socket and is available in the nominal sizes DN 8 to DN 15.
The GEMÜ 566 valve was developed especially for controlling small volumes and provides a flow rate from 63 up to 2500 l/h. For all three actuation types, there are options for optical and electronic position feedback. The motorized version can also be equipped with a positioner. The same applies to the pneumatic actuator, for which a process controller is also available as an optional extra.
