Taco has added a new Multi-Volt Zone Sentry zone valve for use in hydronic heating and other HVAC systems such as those with fan coils and air handlers. The new mechanical valve allows one actuator to accept input voltages between 120 and 277VAC 50/60HZ. The company says this allows for one valve to effectively replace approximately seven standard zone valves. Like the 24VAC version of the Zone Sentry, the Multi-Volt provides similar energy efficient characteristics — for both heating and cooling applications. The valves are available in a normally closed or normally open configuration.
