Rehau® PRO-BALANCE® 260166 Valve Actuator

The 4-wire manifold valve actuator is used to open and close circuit valves on the 1 and 1-1/4 in PRO-BALANCE® manifolds. Use Rehau® thermostats to control actuators directly or connect through Rehau® electronic controls.

Rehau® PRO-BALANCE® Valve Actuator, 24 V, 32 to 140 deg F

• Gray position indicator provides visual verification of the actuators position
• When the actuator is off and closed, the gray indicator is flush with the top of the actuator
• When the actuator is on and open, the gray indicator will rise out of the top of the actuator and be visible from the side
• Red pull-out tab is provided to allow easy installation onto the manifold, after installation remove red tab
• A dry contact end switch is built-in to the actuator
• This end switch can be used to operate 24 V (2 A maximum) relays for pumps and other devices and can be wired so that pumps turn on only when actuator is fully open
• If required, connect the green end switch wires to a suitable 24 V powered relay to activate a device to be operated by the actuator's end switch or connect these wires directly into an appropriate zone control module
• 24 V thermal motor heating element melts a wax cartridge, allowing the actuator to open when there is a call for heat (power on), when the power is off, the wax cools and closes the valve (normally closed), operation takes 3 to 4 min
• Four wires, blue/brown apply 24 V power, green (2) end switch, 40 in L
• Low power draw approximately 2 VA in operation, maximum 4.5 VA when first powered, ensures transformer has sufficient power (VA) to operate all actuators
