A temperature-actuated valve assembly is provided, which includes a valve assembly housing having a main flow passage and a control flow passage. A pneumatically-actuated valve is fluidly coupled to the control flow passage and configured to control fluid flow through the main flow passage. A first thermostatic valve is in thermal communication with the main flow passage and configured to control fluid flow through the control flow passage to position the pneumatically-actuated valve.
