Mount the valve downstream from the coil to minimize heat transfer to the actuator.
Note: Mount the valve downstream from the coil to minimize heat transfer to the actuator. For pure diverting
applications (one inlet/two outlets), only the standard port (no characterization disc) versions will work.
