ASCO 8221G27 1 Inch N/O 5/150# Slow Close Valve .
The ASCO 8221G27 is a 1-inch normally open solenoid valve developed for industrial applications requiring precision fluid flow control. It permits unrestricted fluid passage via the valve when it is activated. The ASCO 8221G27, on the other hand, has a slow-close function that gradually closes the valve to prevent sudden pressure spikes, often known as a water hammer, in contrast to normal solenoid valves that snap shut when de-energized. In HVAC systems, this can be quite important since it shields pipes, pumps, and other equipment from damage brought on by abrupt changes in flow. The ASCO 8221G27, with a 150 psi pressure rating, can be used for a variety of HVAC applications.
