Normally closed means the valve stays closed until power is applied. The high-current auxiliary micro switch closes when the valve opens and can be used to start a circulator or boiler directly.\u003c\/p\u003e\u003cp\u003eBefore ordering, confirm your control voltage is 24V, that you need a normally closed actuator, and that the valve body is a Caleffi Z-One.
