On demand, the valve is opened by a signal from a thermostat (supply voltage on). When the temperature reaches the desired level, the spring return mechanism will force the valve back to closed position. The sealing ball of the valve closes against the flow on the 2-way valves. In 3-way valves, the ball normally closes towards the coil side (see pictures below). On the side of the actuator there is a lever for manually opening the valve
