Hi there,
We are installing a glycol system and as expected running into some issues. Our headers are 1.5 inch and our drop downs are 1 inch. We have installed a valve from supply to return that can be adjusted to release excess pressure. We do not have a VFD to adjust pump speed. when this system is on and none of the tanks are calling for glycol, it runs at 23psi(this is with the PRV being wide open back into the return piping). Is it a bad idea to choke down the valve comping off of the process pump to lower the pressure throughout the system?
