What is the purpose of the powerful spring in a PICV valve?

The powerful spring ensures safe closing of the valve, providing a failsafe mechanism in case of power failure or other emergencies. The spring helps to maintain the valve’s position, preventing unintended opening or closing, and ensuring that the system remains safe and stable. This feature is particularly important in critical applications, such as those found in hospitals, data centers, or laboratories, where system downtime can have significant consequences.
