ABB Valve Positioner V18345-1020121001 Double Acting Actuator
Product Description:
ABB valve positioner V18345-1020121001 is a communication-capable, electronically configurable positioner mounted on a pneumatic straight or angular stroke actuator. It is characterized by small and compact design, modular structure, and has excellent cost performance. The control parameters matching the terminal control elements are automatically determined by the intelligent positioner, which saves a lot of debugging time and achieves optimal control.
Aerodynamic performance:
An I/P module with a rear pneumatic amplifier is used to control the pneumatic actuator. The I/P module converts the positioning electrical signal from the CPU into a pneumatic signal proportionally by adjusting the three-position three-way valve. The adjustment of the pressurization or decompression of the actuator is continuous, so excellent control can be achieved. When the set point is reached, the three-position three-way valve locks in the middle position to minimize air consumption. There are a total of four different pneumatic outputs: single acting and double acting, each available in "fail-safe" and "fail-lock" models.
Fail-Safe function:If the power is off or the signal is broken, the positioner outputs 1 decompress, and the pneumatic actuator returns the spring to operate the valve to a defined safe position. If it is a double acting actuator, the output 2 is also pressurized.
Failure-Block function:If the power is off or the signal is broken, the positioner output 1 (output 2, if any) is locked and the pneumatic actuator holds the valve in its current position. If the air supply is interrupted, the actuator depressurizes.
