Belimo ZONE24NO-S : Zone Valve Actuator

"24V

The Zone 24NoS is a 24V DDC-powered zone valve actuator. It is suitable for installations that require multiple zone valve actuators, for example, in homes and buildings with multiple heating zones or water temperature zones. The control is implemented in the actuator put in series and thus requires two communication lines (24V zones). The system then operates just like a standard single set point control system.

The new Belimo Zone 24NO-S is a 24Vdc 2/2 concept zone valve actuator that is designed as a standard replacement for the commonly used NEXA, Gira, Ideal Standard and Grundfos volume controllers. The 24Vdc actuator is derived from the latest generation of electronically commutated microprocessor controlled actuators and still retains the precision, reliability and field supportability of all previous Belimo classic 2/2 zone valve actuators.

The Belimo Zone Valve Actuator is a ZONE Control Device which can be used instead of the conventional 24V DC proportional devices. The new ZONE24NO-S has many features including the ability to control 2 heater valve actuators with only one temperature controller, ability to provide superheated steam in both heating & cooling mode and a switch-on/off delay up to 15 minutes.

The Belimo Zone Valve Actuator is a panel-mounted ZONE24NO-S type valve actuator with 2 pole normally closed and 2 pole normally open contacts. It has built in adjustable transformer, along with built-in anti-rotation function.

A zone valve is a type of pneumatic actuator that allows control over individual zones for specific applications such as HVAC, environmental systems, or industrial automation. This actuator works on a 24-volt DC power supply and comes with a 30-inch lead. The Zone Valve Actuator has an operational range of 120 psi (1,329 kPa) and provides an output pressure between 10 and 600 psi (70.6 to 4,137 kPa).

The ZONE24NO-S Zone Valve Actuator is an adjustable 0.5P to 5.0P power actuation for zone valves (non-modulating). It is used in conjunction with the ZONE24NOV012-S or ZONE24NOV024-S Valve Coil. The valve coil must be matched to the desired actuator.

The ZONE24NO-S zone valve actuator's robust and reliable operation keeps automation systems running. This device is ideal for automatic control of a mixing valve or recirculating thermostat for a hydronic heating system in buildings with moderate to high traffic.
