Valve Limit Switch Box — NAMUR Mount, 2 SPDT Switches, Open/Closed Indicator, IP67
製品概要
A valve limit switch box that reports whether your valve is open or closed. Two SPDT mechanical switches inside send the position signal back to your control room for remote monitoring and safety interlocks, and the dome indicator on top shows open or closed at a glance.
NAMUR standard mounting — it fits on top of any NAMUR-compatible pneumatic actuator. IP67 enclosure. Tell us your actuator when ordering.

製品説明
Automation only works if you can verify it. This リミットスイッチボックス tells you — and your control system — whether a valve is actually open or closed. It mounts on top of the pneumatic actuator and houses two SPDT mechanical limit switches that trip as the valve reaches each end position, sending an electrical signal back to the control room. A dome indicator on top shows open or closed to anyone standing at the valve.
If a valve fails to reach its position, the switch does not send its signal, and your system can raise an alarm before the fault causes a problem. That makes it a component you rely on for process safety, not just convenience.
What It Does
- Position feedback: confirms open or closed status to the control room for remote monitoring.
- Safety interlocks: lets the system block an action — like starting a pump — until a valve is in the right position.
- Fault detection: a missing signal flags a valve that is stuck or has failed to move.

Why NAMUR Mounting Matters
Because the box follows the NAMUR standard, it is not tied to one actuator brand. The same switch box drops onto any NAMUR-compatible pneumatic actuator, so you can standardize on one position-feedback part across a plant instead of stocking a different unit for every actuator.
使用場所
- PLC / DCS position feedback — the open and closed signals go straight to the plant control system, so operators see valve status without walking to the line.
- Automated valve packages — pneumatic actuator, NAMURソレノイドバルブ and this switch box assemble on one NAMUR interface into a complete automated valve.
- Safety interlocks — downstream equipment such as a pump or heater is held until the switch confirms the valve is in the right position.
- Water and wastewater treatment — remote status on the many valves spread across a treatment plant.
- 化学プラントおよびプロセスプラント — position feedback on process lines that need automated, traceable valve operation.

よくある質問
What does a valve limit switch box do?
It reports the valve’s position. Mechanical switches inside trip when the valve reaches its open or closed end position and send an electrical signal to your control system, so you know the valve’s status without standing next to it.
Is it NAMUR standard?
Yes. It mounts to the NAMUR standard on top of the actuator, so it fits any NAMUR-compatible pneumatic actuator rather than one specific brand.
What type of switches does it use?
Two SPDT mechanical limit switches, one for open and one for closed. They trip on contact as the valve reaches each end position. Contact rating is AC 250 V 16 A and DC 30 V 10 A, and the enclosure is IP67.
Why is position feedback important?
Automation assumes a valve moved when commanded. The switch box verifies it actually did. If the signal is missing, the control system can raise an alarm or hold an interlock before a mis-positioned valve causes a problem.
Which actuators does it fit?
Any NAMUR-compatible pneumatic actuator. Tell us the actuator you are using so we can confirm the fit.
