📌Overview
The ABB V18345-1010521001 Electro-Pneumatic Positioner uses digital technology to control valves through an analog signal and supports HART communication. According to the model code, this specific configuration is double-acting with fail-freeze function, meaning the valve remains in its current position after loss of power and air supply. The positioner is equipped with NPT threaded connections, including a 1/2" electrical connection and a 1/4" pneumatic connection, and has a built-in analog position feedback module.
The positioner supports two installation methods: installation on linear-stroke actuators according to DIN/IEC 534 and NAMUR standards; and installation on rotary-stroke actuators according to VDI/VDE 3845.
✅Features
-
Valve Position Closed-Loop Control:
V18345-1010521001 receives the analog setpoint signal from the control system, compares it with the valve position feedback signal, and outputs a pneumatic signal to drive the actuator. The double-acting structure maintains the current valve position in the event of a fault (fail freeze) and does not automatically move to fully open or fully closed. -
HART Digital Communication:
After the HART communication module is installed, V18345-1010521001 supports the HART protocol and allows remote reading of positioner parameters and valve position information. -
Installation Note:
For linear-stroke installation, the maximum feedback rotation angle of V18345-1010521001 is 60°. For rotary-stroke installation, the maximum angle is 120°, with a minimum rotation angle of 25°. Incorrect angle settings may cause abnormal feedback.
Important Operating Precautions ⚠️
- Reset Requirement: If the positioner has previously been used at another location, the factory settings must be restored before putting the positioner back into operation. It is strictly prohibited to perform the “Autoadjust” automatic adjustment before restoring the default parameters.
- Installation Inspection: Before installation, be sure to check for any damage caused during transportation and ensure that the stroke/rotation angle settings are correct.
