Title: MOTOR OPERATED VALVE
Abstract:
[Problem] To be able to reliably prevent leakage of a fluid in a closed valve state. [Solution] A motor operated valve, which converts rotational motion of a rotor into linear motion by way of a threaded connection of a male threaded member and a female threaded member and moves a valve in a valve main body in the axial direction based on the linear motion, comprises a valve guidance member that guides motion in the axial direction of the valve and a seal member that is interposed between the valve guidance member and the valve, and has a structure that prevents the valve and the valve guidance member from directly contacting each other, by way of the seal member, at least in the closed valve state.
