Currently i have a project that required to use hot standby redundancy PLC, which i think it overkill on my equipment as it is a standalone dehumidifier system.

I like to ask have...

Yes. because my offcoil is at 12degC even when my signal for the valve is 0v.
I tried to close the hand valve on my chilled pipe & my offcoil temperature went up to 21degC. that is how i know the...

I dunno? But i tot 2000N is strong enough to close the actuator valve with chilled water oni at 55psi. cos i tried a siemens actuator with only 1600N and it can fully closed with the pressure is...

It move to 100% position when i give out 10vdc signal and stuck in 30% open position when i give 0vdc signal. But my staff siad it sometime won't move at all when they test it again.

Hi guy,

I'm using a Belimo "AV24-MFT2" actuatuor with 2000N. :eek: My problem is it can't fully close when my signal output is 0Vdc. The chilled water supply pressure is only 55psi & 50psi for...
