The GEMÜ R563 eSyStep 2/2-way straight seat control valve as a body with integrated control mechanism. The GEMÜ R563 eSyStep was specially developed for the control of small quantities and allows a flow rate of 63 l/h up to 3300 l/h. The valve is available with a positioner for a 0/4-20 mA or 0-10 V input signal and can also be configured to a safety position with the use of an emergency power module. Further functions can be customised via the IO-Link interface. The self-locking actuator maintains a stable position in the controlled state and in the event of a supply voltage failure.
