Badger Smart Electric Valve Actuator
Badger Meter has launched its new next generation Badger Smart Electric Valve Actuator. The SEVA actuator is built with military grade components to withstand extreme conditions while the microprocessor-controlled linear stepper motor gives the accuracy, repeatability and reliability for precise control.
Two models are available with 135Nm (SEVA – 100) and 270Nm (SEVA – 200) torque suitable for 1/4” – 2” Badger Research Control valves. The actuators have options for EtherNet/IP and ModBus TCPIP/RTU protocols 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. The actuators allow for both linear and Device Level Ring (DLR) network protocols for greater feedback required for some systems.
The actuators are designed for extreme conditions and provide accuracy of (±1% of full scale) for precise applications using a loop-powered feedback signal. The actuators feature four positions when there is a loss of signal; fully closed, fully open, hold position, or set value. Both the full closed and full open positions are defined during set-up, and in the event of loss of power, there are five available positions available; continue operation, fully closed, fully open, hold position, or set value, and also a manual override capability.
Flameproof and ATEX EEx d versions are available.
