Key Features

The V18345-1010120001 offers several advantages for valve positioning applications.

Intelligent TZIDC Platform:
The positioner is fully configurable with an indicator and operator panel. Therefore, local configuration and diagnostics are straightforward.

Versatile Mounting Options:
Mounts to linear actuators per DIN/IEC 534 / NAMUR. Additionally, it mounts to rotary actuators per VDI/VDE 3845. Consequently, one positioner suits many actuator types.

Robust Aluminum Housing:
The case is made of varnished aluminum with IP65 / NEMA 4X protection. Hence, it resists dust and water ingress in harsh environments.

Wide Operating Temperature:
Operates from -40°C to +85°C. For this reason, it suits outdoor and extreme climate installations.

Low Air Consumption:
Consumes less than 0.03 kg/h independent of supply pressure. Thus, it reduces operating costs compared to higher consumption positioners.

Flexible Signal Configuration:
Supports increasing or decreasing signal action. Moreover, split-range operation is freely selectable. As a result, it adapts to various control system requirements.

Multiple Characteristic Curves:
Offers linear, equal percentage (1:25, 1:50, 25:1, 50:1), or freely configurable with 20 reference points. Therefore, it matches virtually any valve characteristic.

Adjustable Travel Limit:
The positioning travel can be reduced within 0-100% range. However, a minimum value of 20% must be observed.

Shut-Off Function:
Configurable separately for each end position. When the limit value is exceeded, the positioner drives the actuator to the set end position. Consequently, tight valve shut-off is achieved.

Travel Time Prolongation:
This function increases the maximum travel time for full travel. Furthermore, the time parameter can be set separately for each direction.

Action and Characteristic Curve Options

The V18345-1010120001 offers flexible positioning response.

Positioning Signal Action:

• Increasing: Signal 4-20 mA = position 0-100%.

• Increasing: Signal 20-4 mA = position 0-100%.

Characteristic Curves:

• Linear.

• Equal percentage 1:25 or 1:50.

• Equal percentage 25:1 or 50:1.

• Freely configurable with 20 reference points.

Typical Applications

The V18345-1010120001 suits a wide range of valve control applications.

• Linear control valves in chemical processing plants.

• Rotary actuators in oil and gas facilities.

• Pneumatic valve positioning in power generation.

• Industrial automation requiring precise valve control.

• Retrofit of existing valve assemblies with TZIDC technology.

Installation Guidelines

Install the V18345-1010120001 according to standard pneumatic positioner practices. First, mount the positioner to the actuator using the appropriate mounting kit. For linear actuators, follow DIN/IEC 534 / NAMUR guidelines. For rotary actuators, follow VDI/VDE 3845 guidelines.

Connect supply air at 1.4 to 6 bar (20 to 90 psi). The air consumption is less than 0.03 kg/h. Then, connect the 4-20 mA control signal to the analog input terminals. Use 2.5 mm² maximum wire size.

For the digital input, apply 11-30 V DC for logic "1" or 0-5 V DC for logic "0". The digital output provides 5-11 V DC per NAMUR DIN 19234.

Configure the positioner using the indicator and operator panel. Set the action (increasing or decreasing), characteristic curve, travel limits, and shut-off parameters as required. Finally, perform an auto-calibration to match the valve's stroke characteristics.
