ABSTRACT:
An improved inflatable bladder for use as a zone climate control system valve to controllably permit and prevent airflow through a vent of a forced air HVAC system. The bladder is secured by a rigid strap which may be coupled to the vent near the vent opening. The bladder is coupled to its pressure/vacuum air tube by a pin which is inserted through the air tube and the bladder nipple to which it mates. The bladder may have a donut shape for use with a vent which is located directly on a trunk which also has downstream vents or ducts which are not part of the same zone as the vent controlled by the bladder.
