ASCO 821437CSA 3/4 Inch N/O Vent Valve ,0/5#

The ASCO 821437CSA is a 3/4-inch, normally open vent valve that controls air or inert gas flow in HVAC systems and other industrial applications. The valve opens to let air out when the pressure decreases to zero PSI. On the other hand, it shuts when the pressure hits 5 PSI, stopping backflow. Pressure control and optimal system performance are ensured by this straightforward but efficient design. Consider a situation where your air conditioner experiences an increase in pressure. By automatically opening, the ASCO vent valve releases pressure and guards against harm to your equipment. It can also be used to control airflow in vacuum lines, pneumatic systems, and other industrial operations. The durable aluminum construction and NBR seals of this valve ensure reliable performance across various conditions.
