Please recommend a limit switch for manual stop valves
Thread Content
Several manual stop valves on the device require feedback on their on/off status; limit switches need to be installed. I haven’t encountered this issue before, so please recommend any relevant information or products. Thank you!
We are the purchaser, and we have had extremely demanding requirements; it seems to be something similar to the dial on a gearbox valve
Reference can be made to the linear-stroke knife gate valve, with limit switches installed at the upper and lower switching positions.
Thank you, it needs to be able to be transmitted to the control system via electrical signals
Thank you. For these limit switches, there are contact-type and non-contact-type versions – I’m not sure which one is better as it’s important to have accurate feedback. I’m worried that the limit switch may indicate that the valve is closed, when in fact it isn’t fully closed
Indeed, the limit switch of the knife gate valve can be used; no problems will arise after installation
For a manual valve, I don’t think a limit switch is necessary; it’s sufficient if the switch is in the correct position
For this type of limit switch that requires signal feedback, a small sensor needs to be installed; valve manufacturers provide such sensors as part of their products.
Thank you; the control system is used for protection purposes
