An easy way to see if the valve is opening is: While the thermostat is set well above room temperature, you should be able to move the lever on the zone valve almost all the way very easily. If you cannot without feeling spring resistance, the valve is not opening. Further trouble shooting of the valve motor would require the use of a voltmeter to see if you are getting 24 volts to the motor.
