Re: [Fwd: automatic 2 way valve]

In my previous experience, I haven't encountered an automatic valve that is operated by "temperature" only. Differential temperature or pressure will only send signals to the sensor to activate the valve actuator/positioner. Valve actuators are electrically or pneumatically activated because of the "torque" required.
