How does the anti-stall valve operate when the circulator is checking the inlet flow rate?
Disengage the surge interlock; our surge system has an interlock for low flow. If the flow meter is checked, the interlock will be disengaged, or the on-site surge valve should be switched to manual mode!
Even in manual mode, the anti-surge valve will open once the compressor starts surging
Will the anti-surge valve also operate when set to manual?
The anti-surge valve isn’t related to the inlet flow rate of the circulator, right? Isn’t it true that this valve only opens when it’s not possible for the circulator to pump fluid out?
