The GEMU 520 actuated globe and control valve is now also available in smaller nominal sizes DN 32, 40 and 50.

GEMU 520 is particularly suitable for use as a control valve for steam, air, water and process lines on account of its membrane actuator. The existing sizes DN 65 – 150 are now extended to smaller nominal sizes DN 32 – 50 to meet customer requirements. New actuator/valve body versions have also been developed to further increase the range of applications. In sizes DN 32 – 65 the valve can now be used with up to 40 bar operating pressure with valve bodies in cast steel GP 240 H and stainless steel 1.4408. Further new options include valves which can be actuated with a considerably reduced control pressure of 1.5 – 4 bar, depending on nominal size and operating pressure. The matched GEMU range of autoset valve positioners provide complete throttling control via PLC or on-board process controllers.
