Thermo-electric actuator

with low current draw

6564 series

01198/14 NA

Function

The thermo-electric actuator, mounted to a zone valve or manifold,

allows automatic shut-off of the medium under the control of a room

thermostat or electrical switch. The 6564 series features low current

draw, ideal during the start-up phase.

It is equipped with a valve opening/closing indicator, and a quick-

coupling system with a retainer clip adapter for easy installation.

Itfeatures NEMA 5 protection allowing upside-down installation.

Operating principle Protection class NEMA 5 When the power supply is OFF, the device (actuator + valve) is “normally closed” with the valve plug (1) pushed against the seat. When the power supply is ON, the valve opens as the wax thermostatic element expands (2) controlled directly by a PTC resistor (3). The protection class of the 6564 series thermo-electric actuator, assembled on the valve, is NEMA 5 (IP 54).
PAGE 3
˜ Low starting current 6564 series valve or manifold assembly characteristics The 6564 series thermo-electric actuator features a low starting (in‑rush) current. This prevents having to oversize the power transformers to supply a high number of actuators, connecting them to common control devices such as controllers and thermostats.
