Abstract
A mechanical thermostatic refrigerant expansion valve assembly with an electrically operated shut-off in the inlet to the valve body. Preferably, the electrical operator is a solenoid attached to the valve body on the end opposite the mechanical thermal responsive valve actuator so as to minimize the changes in the manufacturing of an existing valve body. The solenoid armature moves a secondary valving member spring biased to shut off flow in the valve inlet.
