WHERE TO LOCATE A PRESS ACTUATED WATER REGULATING VALVE
WHERE TO LOCATE A PRESS ACTUATED WATER REGULATING VALVE
(OP)
Hi all ,
As ever I see , when puting a regulating flow valve it is done downstream the condenser , or heat exchanger.
As the usually used GLOBE VALVE , it run too when regulating the pump flow.
For a PRESSURE ACTUATED WATER REGULATING VALVE.
There is any reason a valve vendor state it as follow:
"Mount vertically with elbows down, ON THE INLET SIDE of condenser.""

Good Question!
Even though the instructions for Johnson Controls (Penn) water regulating valves say to mount the valve on the inlet we always mount it on the outlet, thus regulating the flow leaving the condenser (shell & tube). This insures that the shell is full of water at all times during operation.
Besides it seems to be the right way to begin with. Been doing it this way for a very long time.

Would you please tell me where it is such information.
BTW , this afternoon I talk with the vendor's dealer in my city , and the only razon to state to put at the inlet , is because it is assumend that the water pressure is high enough to fill the circuit , but despite that instruction , he recomend to install down water the condenser.
Except for diverting valves , all regulating valves 2 or 3 way shall be instaled at the outlet.
Thanks for you answer

"If it is necessary to keep the condenser flooded with coolant, the valve can be mounted on the outlet side"
Good Luck
