1. A control valve for regulating a fluid flow in an HVAC system, the control valve comprising:
a valve body and a temperature sensor configured to measure the temperature of a fluid flowing in the control valve,
wherein the temperature sensor is arranged such that the temperature sensor is essentially thermally decoupled from the valve body, and
wherein the temperature sensor is mounted in the control valve by an at least partially thermally insulating fastener,
the contact between the fastener and the valve body is established via a thermally insulating portion of the fastener,
the valve body comprises a valve regulating member, the valve regulating member being adjustable between a closed position and an open position to vary the fluid flow through the valve body,
the fastener is mounted on or within the valve regulating member such that a front part of the temperature sensor is arranged within the valve regulating member,
the fastener comprises a thermowell configured to receive the temperature sensor, and
the thermowell comprises a thermally conductive head arranged in an interior space of the valve body, the head being thermally coupled to the temperature sensor.
