Abstract
This is a valve for controlling fluid flow in a conduit in which a valve plate member is moved in and out of engagement with a valve seat in a nozzle in the conduit by means of a thermal actuator to close and open said valve in response to temperature changes in said fluid. The valve plate member is carried by a housing of the thermal actuator and moves relative to a stem that extends from the housing. The free end of the stem is secured by means of a lamina that bridges the nozzle, the plane of said lamina extending in the direction of fluid flow through said nozzle.
