## Summary description

Two-way zone valve CALEFFI 642062 with actuator and built-in auxiliary microswitch. Designed to control flow in heating and cooling zone systems, the valve provides on/off regulation of circuits via its actuator and gives an electrical signal through the auxiliary microswitch for system integration, status feedback or interlocking with controllers and pumps.

## Long description

The CALEFFI two-way zone valve with actuator and built-in auxiliary microswitch is designed for on/off control of heating and cooling zones. The compact assembly integrates a modulating actuator and an electrical microswitch to provide both hydraulic shut-off and an electrical feedback signal for system controllers, pumps or interlocking circuits. The product is suitable for installation in residential and light commercial hydronic systems where reliable zone isolation and status signalling are required.
Advantages
This two-way zone valve combines valve actuation and an auxiliary microswitch in a single compact unit, reducing installation time and wiring complexity. The integrated microswitch provides a clear electrical contact signal for controller logic or pump interlock, enabling straightforward status monitoring and automation. The valve mechanism is engineered to ensure tight shut-off and consistent on/off operation that helps maintain stable zone control.
Suitable for
Control of individual heating or cooling circuits in hydronic zone systems
Integration with room thermostats, zone controllers or building automation systems
Interlocking pumps or other equipment based on valve position feedback
Replacement or upgrade of existing two-way zone valves in residential and light commercial installations
Key specifications
Configuration: two-way zone valve with actuator
Function: on/off zone control with electrical status contact
Integrated signal: auxiliary microswitch providing electrical contact for position/status feedback
Application: hydronic heating and cooling circuits
Mounting: in-line installation on supply or return pipework (inline valve body)
How to use
Install the valve in the pipework following standard hydronic installation practice, ensuring correct flow direction and secure mechanical connections. Connect the actuator electrically to the control signal as specified by the system controller and wire the auxiliary microswitch into the control or pump interlock circuit according to the control schematic. After installation, operate the thermostat or zone controller to confirm that the actuator opens and closes the valve and that the microswitch changes state to provide the expected electrical feedback.
Usage recommendations
For reliable operation, ensure the valve is installed in accessible locations for future maintenance, protect electrical connections from moisture, and follow local regulations for wiring and system integration. Verify compatibility of control voltages and contact ratings between the auxiliary microswitch and the connected controller or pump relay before final commissioning.
