Smart control valve for minimal flowrates and high pressures
Low-flow valves or needle valves are always used wherever minimal flowrates or high pressures have to be controlled with particular precision or securely shut off. With the type 7042 (photo, p. 43), this company has now developed a low-flow valve that not only offers minimal Kv values of 0.0027 to 1.7 and a nominal pressure of PN320, but also impresses with state-of-the-art field integration. The 7042 shows its full potential together with the optionally integrated positioner type 8049. In addition to an explosion-protected and FM version, it can also be equipped with an IO-Link connection or industrial internet of things (IIoT) module. With IO-link, a single cable with an M12 plug bundles the positioning signal, position feedback, data transmission and even the power supply. The continuous monitoring of the status data allows even the slightest irregularities in the control behavior to be detected.
