<p>A unit of a motor type flow control valve, comprising a motor installed in an external resin, a mechanism converting the rotation of the motor to the linear motion of an actuator rod, bearings supporting the motor rotor, and a bearing guide, wherein the unit is installed at one end of a valve body and the rod is connected to a valve stem (4), a bearing guide (good heat conducting member) is brought into contact with the stator parts of the motor and also into contact directly with the inner periphery of the valve body or indirectly with it through the good heat conducting member, the valve disk is formed separately from the valve stem and fixed by welding after positionally adjusted by loose fitting, whereby the relative initial position of the actuator rod to the valve disk of the motor type flow control valve can be determined easily and, in addition, the radiation capability of the motor can be increased to increase the performance of the flow control valve, and the device can be reduced in size and the assemblage of the device can be facilitated.</p> |
