Factsheet

Series Number 612
Series Name Butterfly valve control system
Description Butterfly pressure control valves for downstream applications. Very fast and strong actuator. High-performance, integrated controller. Extremely short control response times and position indication. Automatic maintenance indication. Service port (conection for computer or service box 2 connection). Excellent resistance to contaminating processes.
Actuator types Stepper motor, integrated controller
Sealing technology Rotary feedthrough (double seal)
Feedthrough Rotary feedthrough, (Viton)
Leak rate body < 1 . 10-9 mbar ls-1
Nominal inside diameters (ID) in mm (inch) 25 (1") - 250 (10")
Body material Aluminium hard anodized; Aluminum; Stainless steel
Cycles until first service 2 million cycles unheated and under clean conditions
Pressure control The controller ensures very fast and accurate pressure control. By operating the LEARN function — needs to be done only once at start-up — the system parameters are automatically determined. Due to the adaptive algorithm the controller continuously adapts to the process conditions (species of gas, gas flow) and thus ensures optimum pressure control at any time.
Position control In position control mode the valve plate can be moved to any position.
Remote operation The valve can be controlled by a host computer via RS232, RS422, RS485, Logic, DeviceNet®, Ethernet, Profibus, CC Link or EtherCAT interface.
The RS232 interface and the field busses also have digital inputs to close and open the valve. In addition, digital outputs are available for «open» and «closed» (status of valve).
Control via Logic interface performs via digital and analog inputs and outputs.
Display Status and position are displayed by means of 4 bright digits.
Service Port The valve has a service port (RS232) for «Local operation» to connecting a computer or a service box or a control panel. VAT can provide two software versions which, independent of the hoster computer, allow a variety of functions.
For connecting the computer to the valve, a special cable designed by VAT is required.
Power Failure Option (PFO) This function is optionally available. It closes (to the minimum conductance) or opens the valve automatically at power failure.
Sensor Power Supply (SPS) Optionally, the valve can be provided with a ±15 V DC power supply unit for the sensor/s.
