The ITS-100 limit switch box is designed for valve position monitoring in pneumatic actuator systems used in industrial automation and process control. It provides reliable open/close feedback signals and visual position indication for quarter-turn valves such as ball valves, butterfly valves, and plug valves.
Installed directly on the valve actuator, the ITS-100 converts mechanical valve rotation into electrical switching signals. These signals are transmitted to PLC or DCS control systems to ensure accurate valve status monitoring in real-time operating environments.

Industrial Valve Position Feedback
In automated process systems, accurate valve position confirmation is essential for safe operation, interlock control, and system diagnostics. The ITS-100 is widely used in applications where stable switching performance and clear visual indication are required under continuous operating conditions.
Typical industrial applications include:
- Oil and gas pipeline systems
- Petrochemical and refinery plants
- Water and wastewater treatment systems
- Power generation facilities
- Chemical processing industries
- General industrial automation systems
The device helps reduce operational risk by ensuring that valve position signals remain consistent and readable even in harsh field environments.
Rugged Housing for Harsh Environments
The ITS-100 is built with a durable housing designed for industrial field conditions. It is available in aluminum die-casting or stainless steel (304/316), depending on corrosion resistance requirements.
- Aluminum housing: suitable for general industrial environments
- Stainless steel housing: suitable for offshore, chemical, and high-corrosion applications
The enclosure is rated IP67, providing protection against dust ingress and temporary water immersion. This ensures stable operation in outdoor installations and exposed valve stations.
Clear Visual Position Indication
The ITS-100 features a high-visibility mechanical indicator for valve status identification:
- Yellow: valve open position
- Red: valve closed position
This allows maintenance personnel and field operators to quickly verify valve status without connecting to control systems.
Electrical Connection and Cable Entry
The ITS-100 supports multiple cable entry options to accommodate different international installation standards:
- 2 × 1/2" NPT
- PT1/2
- PF1/2
- M20
- PG13.5
This flexibility simplifies integration into different actuator and control system configurations.
The ITS-100 limit switch box is designed for reliable valve position feedback in industrial environments where durability, stable switching performance, and simple field maintenance are required. It is suitable for continuous-duty automation systems where consistent valve status indication is critical for safe and efficient operation.
