A thermostatically operated valve uses a valve insert screwed into a tube-shaped stud at a valve housing. The valve insert comprises two spaced-apart valve seats which are located on opposite walls of a chamber provided within the valve insert series-connected in a flow direction with one seat forming a control valve seat and the other seat forming a shut-off valve seat. Between the valve seats, a valve closing body is arranged within the chamber for temperature control operation by a thermostat device. The outlet of the valve is connected to a chamber downstream of the shut-off valve seat and a throttling bore connects the chamber between both valve seats with the outlet of the valve. A removal of the thermostat device allows the valve closing body to be urged against the shut-off valve seat by a spring within the valve insert while maintaining a flow through the throttling bore.
