Description
SMVI Intelligent Control Valve
A line of electronic two-way metering valves is presented. High precision linear stepping motors drive the valve spindle. The resolution of the stepping motor driven needles is 0.000125″/step. Low differential pressure valves, may be operated continuously (100% duty cycle). Valves stay in position as when de-energized.
Design Features
- Improved high-precision two-way metering valves in aluminum or 316 SS for gas/liquid applications
- Four different control modes and multiple analog interfaces are supported to accommodate the variety of customer applications
- Standard digital RS-485 interface implemented using galvanically isolated RS-485 transceiver with high common-mode transient immunity allows direct digital communication with PLC or PC and provides access to all configuration and process variable parameters
- ASCII commands set, free Communication and Configuration software, and LabVIEW Driver
- Eliminates problems associated with solenoid designs, such as coil heating and electromagnetic hysteresis
Specifications:
- Analog Interface (0-5Vdc, 1-5 Vdc, 4-20mA, 0-10Vdc* options are supported). The valve opening is linearly proportional to the control analog signal in this mode.
- Digital RS-485 Interface (via optically isolated transceiver using proprietary ASCII commands set). In this mode, the user can control the valve by sending the command with the desired valve opening position expressed in % of valve full opening (0.00 to 100.00% with 0.01% resolution).
- Direction / Speed (legacy SMV valve proprietary mode). In this mode valve is controllable using digital TTL (low active) “Direction” and analog (0-5Vdc, 1-5 Vdc, 4-20mA, 0-10Vdc* options are supported) “Speed” signals.
- Step Clock / Direction. In this mode, the valve is controllable using digital TTL (low-active) “Step” and “Direction” signals. With each falling edge on the “Step Clock” input, the valve needle will move one step to close or open direction based on the logic level applied to the “Direction” input.
