Isolation By-pass Valves
Installation Examples
Straight and 90° angled isolation /by-pass valves are available (sold separately)
Straight valves are designed for through the floor piping and 90° angled valves for through the
wall.
Isolation/By-Pass valves isolate the radiator (from the piping system, allowing quick and easy
maintenance). They also allow radiators to be piped using one pipe systems incorporating the
optional thermostatic operators. Each valve is factory set at 35% flow through the radiator
and 65% through the by-pass. Additional adjustment can be accomplished by adjusting the
by-pass screw with a 5mm allen wrench. Turning the adjustment clockwise increases water
flow through the radiator. To set the adjustment screw back to the factory setting, turn it
clockwise to the fully closed position, then turn it counter-clockwise 1 3/4 turns.
