Two-wire thermal actuators for TruFLOW Classic and Jr. Valved Manifolds

Two-wire, slow-opening thermal actuators mount directly onto TruFLOW Classic and TruFLOW Jr. valved heating manifolds to provide individual-loop flow control on a multi-zoned manifold (a manifold serving more than one zone). Note: See actuator-to-manifold compatibility table on page 96.
