The Orkli Motorised Zone Valves are designed to operate as on-off regulators in closed water circuits in central heating, hot water and climate control installations. These two way valves are direct flow valves, where the circulation is normally closed when powered down. When power is applied the valve opens and the microswitch closes (if there is one fitted). In the event of a power failure the valve automatically returns to the closed position. In this case a cam enables the valve to be operated manually, as well as for the filling, bleeding and emptying of the system.
