    Are you looking for a PICV or just a manual balance>

    Pressure Indépendant Control Valve combines an on off function with pressure independant balance, auto balance so to speek. Any zone valve with a pressure independant balance down stream accomplishes this.

    Chose the brand and type of ZV you like and add a 127 AutoFlo valve to it.

    Depends on what type of control you are looking for.

    I have to add a radiant zone to a remote manifold station. The manifold station is home built with 2" pipe and 3/4" radiant tubing, no head loss to speak of. The radiant zone I am adding has a head loss of approximately 6'. There will be one pump with 2 zone valves, since it is a minitube injection system. For that reason, I need to impose a flow restriction on the original manifold, and balance the 2 radiant zones. I have limited space, which is why I am looking into a combination zone/balance valve.
