Manual Valve Position Indication

The Aloxy valve monitoring solution is built up in three parts, the IIOT platform, the communication infrastructure and the Aloxy Pulse sensors.

The IIOT platform is hosted in the cloud or on premise and is required to accurately determine the valve positions based on the sensor data. The platform is used for device management, network monitoring, data integrity and battery life time optimization.

The sensor communicates with the IIOT platform through a low power wireless network. For this network, Aloxy can use different protocols such as LoRaWAN and DASH7. There is no silver bullet technology, therefor depending on the application and site specifics an analysis is done to select the proper network technology. Aloxy can provide gateways with specific unique capabilities to communicate LoRaWAN as well as DASH7 simultaneously. However third party gateways can be used as well.

The Aloxy Pulse sensor to capture the valve data is a unique solution for manual valves to monitor the position, location, temperature and vibration for all types of manual valves. The sensor can be mounted to the valve without alterations to the valve or the need for unique mounting brackets.

The industry challenge.

Wrong valve positions are risky.

Incidents and accidents

Process downtime and production loss

How does it work?

The Aloxy valve monitoring sensor is a disruptive technology using different inertial sensors to collect raw data, a patent pending algorithm is implemented to translate this into an accurate valve position signal.

The use of this unique methodology provides unique advantages when applying the sensor on a valve resulting in a unique low-cost solution to get accurate wireless manual valve position feedback.

Easy Mounting

The sensor can be mounted anywhere on the moving part (hand-wheel or lever) of the valve. This creates enormous flexibility in mounting and does not require you to measure the valve dimensions upfront or build customized brackets reducing installation cost significantly.

Universal mounting

Plug and play

Once the sensor is installed it can be easily calibrated in either the open or the closed position by using the sensors push buttons. Once calibrated in its current position, it is not required to operate the valve to finalize the installation. In case the valve cannot be operated, the opposite position is automatically calibrated after the first full operation.


Intermediate position indication

The Aloxy solution provides open, closed and intermediate valve position feedback in a percentage of open. This also creates additional data in your valve operations and valve behavior. When a valve is only 98% closed or 102% closed, this can give additional insights in wear and tear of your valves.

Dual Position


A typical chemical or oil & gas company has various use cases for manual valve positioning that can be made economical viable nowadays through IoT. In general, the IT and OT systems remain clearly separated and the valve position information generated is strictly used for IT.


The Aloxy Pulse complies with the essential safety requirements of the European ATEX Directive 2014/34/EU and the US / Canada FM certification Class1 Div2

The real time position of many manual valves in often unknown and can only be identified by walking the line and visually recording the position to confirm the line up is done correctly.

Having the correct valve position available in real time increases safety, reliability and efficiency

Additionally, logging the manual valve operations generates additional understanding of manual valve operations, creating additional insights that contribute to increase efficiency in plant operation The current sensor can also be attached to critical assets (e.g., valves) to monitor regular maintenance or turnaround progress and track the location of the asset. This can be used to create real time progress and analyse turn arounds to increase efficiency.

Increase efficiency

Going outside to check the position of manual valves is very time consuming


Increase reliability

Visual checks remain vulnerable to human error and negligence


Increase safety

No visual checks are required and as a result less personnel is exposed to danger unnecessary
