Product launch for GEMÜ R563 eSyStep control valve

11 January 2021

GEMÜ, a manufacturer of high-quality valves, measurement, and control systems, launches the GEMÜ R563 eSyStep, a new control valve with a motorized actuator. The valve specialist has also expanded the GEMÜ 566 control valve with the GEMÜ eSyStep actuator. 

The GEMÜ R563 eSyStep control valve is preferably used for control applications with low flow rates. With Kv values from 63 l/h to 3300 l/h, it is possible to react to customer-specific control parameters. Due to the use of selected plastics and elastomers in the media wetted area, the valve has a wide range of uses and can be used with a wide variety of media, for example for supplying water for mixing precise ratios of acid and lye in ion exchangers.

The GEMÜ 566 control valve can also be used to control minimal volumes thanks to its Kv values of 63 l/h up to 2500 l/h, each with an equal-percentage and linear control characteristic. The separation between the media wetted area and the actuator component is achieved by an isolating diaphragm. The diaphragm is available in EPDM or FPM materials. In addition to the pneumatically and manually operated actuators already available, a design with the GEMÜ eSyStep motorized actuator will also be available in the future.

GEMÜ eSyStep is a universal actuator for open/closed and simple control applications and consists of a compact spindle actuator with a stepper motor and an integrated IO-Link interface for exchanging process data. A positioner is integrated as standard. Further components and accessories can be fitted using an interface. An emergency power supply module can be used to configure the actuator to a safety position. The self-locking actuator holds its position stably when idle and in the event of power supply failure. The actuating speed is a maximum of 3 mm/s. The actuator is also used in the GEMÜ 543 angle seat globe valves and GEMÜ 533 straight globe valves.
