Danfoss water valve
Hi everyone.
I recently installed a water chiller to cool a solvent reclaimer, trouble is the machine was originally cooled on a total loss basis (costing my customer over £2000 p/a for water) so the condensor pressure was simply controlled by regulating in inlet water flow via a Danfoss WVFX valve.
The situation now is that with the chiller and reclaim m/c running the Danfoss valve will be shut until the head pressure rises enough to open it. Until it opens the chiller pump will be pumping against a dead end.
I`m going to install a bypass but I need to shut the bypass off as the head pressure rises to force the water through the condensor.
Now here`s the question: Can I reverse the operation of the valve ie it closes on rising pressure? I seem to remember reading somewhere that it`s possible but I`m dammed it I can find it now.
Many thanks guys
