WebbDanfoss thermostatically operated valves are a simple and reliable control solution requiring neither electricity nor control air. The range of thermostatic valves includes a series of industrial products for both cooling and heating controls. The valves are self-acting, i.e. they operate without the supply of auxiliary energy such as ... WebbThe system is driven by a self-acting control system, which releases a compressed spring in the high limit cut-out unit and snaps the isolating valve shut if the pre-set high limit temperature is exceeded. The fail-safe actuator unit does not drive the control valve directly, but a shuttle mechanism in thehigh limit cut-out unit instead. flattering glasses for round faces
