actuator

To obtain the precision required of many PLC flow control systems, Badger Meter has launched its next-generation Smart Electric Valve Actuator (SEVA).  Available through PUMP ENGINEERING, the actuator is built with military grade components to withstand extreme conditions while the microprocessor controlled linear stepper motor provides exceptional positional accuracy to give the reliability, accuracy and repeatability needed.

Two models are available with 100ft-lb (135Nm) and 200ft-lb (270Nm) thrust options suitable for 1/4” – 2” Badger Research Control valves.  The actuators utilise the Industrial Ethernet Protocol (EtherNet/IP) and are certified by the Open DeviceNet Vendors Association (ODVA). SEVA actuators feature a dual-port Industrial Ethernet card and can be set-up via the built-in firmware or via a USB port.  For applications which require a higher level of information for their control systems, the actuators allow for both linear and Device Level Ring (DLR) network topologies.

The actuators are designed for extreme conditions and provide accuracy of (±1% of full scale) with 5 available positions when there is a loss of power; continuous operation, fully closed, fully open, hold position, or target value. They also feature 4 positions when there is a loss of signal; fully closed, fully open, hold position, or target value. Both the full closed and fully open positions are defined during set-up.

In addition, for precise applications, the SEVA offers a loop-powered feedback signal which actively communicates stroke position to the control system, it also features a manual override capability to help operators when there is a loss of power.

The actuator assembly provides the option to include 2 user-adjustable limit switch outputs, while an external signal is provided once the set points of the limit switch are met. Furthermore, it can split the incoming 4-20 mA signal and use either the lower or higher range of the signal for full stroke operation.

SEVA was specifically designed to minimise the number of models needed to work with different electrical demands. Its universal AC input with voltage protection will work with 115 VAC, 230 VAC and 24 VDC power supplies which ensures the confidence that it will provide a single source for different process needs. SEVA can receive analog input signals from 4-20 mA, 0-5 VDC or 0-10 VDC.

They are available with FM or ATEX EExd IIB T6 approvals for hazardous areas and are IP66 rated.
