Baruff signal feedback butterfly valve

1、 Product Overview

Baruff signal feedback butterfly valveIt is a valve that integrates position feedback function, mainly used in industrial automation systems. It can monitor the opening, closing or intermediate position status of the valve in real time and transmit signals to the control system. This type of valve is widely used in industries such as water treatment, chemical, food and beverage, and pharmaceuticals.

2、 Technical parameters

1. Valve TypeClamp on butterfly valve.

2. Nominal DiameterDN50 to DN600 (specific models may vary).

3. Nominal PressurePN10, PN16 (higher pressure rating can be selected according to the model).

4. Applicable MediumWater, gas, oil, weakly corrosive liquids, etc.

5. Applicable Temperature-20 ℃ to+150 ℃ (depending on the sealing material).

6. Valve body materialStainless steel (such as 304, 316), carbon steel, etc.

7. sealing materialEPDM, NBR, PTFE, etc.

8. Signal feedback type：

• Switching signal (such as NPN/PNP output).

• Analog signal (such as 4-20mA or 0-10V).

• Digital signals (such as IO Link).

3、 Structural characteristics

1. Integrated sensor technology：

• Built in non-contact sensors (such as magnetic induction or Hall effect sensors) are used to detect the position of the valve plate.

• High precision feedback and strong anti-interference ability.

2. modular design：

• The sensor module can be replaced separately for easy maintenance.

• Supports multiple communication protocols such as IO Link, Profibus, Profinet, etc.

3. Protection level：

• Usually IP67, suitable for harsh environments such as humidity and dust.

4. Installation method：

• Clamp on installation, compact structure, space saving.

• Supports horizontal or vertical installation.

4、 Signal feedback function

1. position detection：

• Real time monitoring of the opening, closing, or intermediate position of the valve plate.

• Multiple position points can be set (such as 0 °, 45 °, 90 °).

2. signal output：

• switch outputUsed for simple on/off status feedback.

• Analog outputUsed for continuous position monitoring (such as 4-20mA corresponding to 0-90 °).

• Digital CommunicationTransfer more information (such as valve status and fault diagnosis) through protocols such as IO Link.

3. fault diagnosis：

• Sensors can detect abnormal states such as valve jamming and position deviation.

• Remind maintenance personnel through signal output or communication protocol.

5、 Installation and Debugging

1. Installation requirements：

• Ensure that the valve is aligned with the pipeline flange and the bolts are evenly tightened.

• Prevent the sensor module from being affected by mechanical shock or high temperature.

2. Debugging steps：

• Connect the power and signal lines.

• Set the feedback signal type and range through the control system or handheld device.

• Test valve action and confirm accurate signal feedback.

6、 Maintenance and upkeep

1. regular inspection：

• Check if the sensor module is loose or damaged.

• Clean the surface of the valve to avoid dust or oil stains affecting the performance of the sensor.

2. Fault handling：

• If the signal feedback is abnormal, check if the wiring is correct and if the sensor is aligned.

• Replace the sensor module or contact technical support if necessary.

7、 Application Cases

1. water treatment system：

• Used to control water flow, monitor valve status in real-time, and ensure stable system operation.

2. chemical industry：

• Reliable control is achieved in corrosive media through stainless steel valve bodies and corrosion-resistant sealing materials.

3. Food and Beverage：

• Compliant with hygiene standards and suitable for sterile environments.

8、 Selection suggestions

1. Select the appropriate valve model based on pipeline size and pressure rating.

2. Select the signal feedback type (switch quantity, analog quantity, or digital communication) according to the requirements of the control system.

3. Consider the characteristics of the medium (such as temperature, corrosiveness) when selecting valve bodies and sealing materials.
