What are the requirements for the opening pressure of a check valve?
Reply #22019-07-05
There are different types of check valves; the typical ones are gravity-type and spring-type, with the opening pressure determined based on the system requirements. For the gravity type, it is determined based on the floor height and the installation height of the valve; for the spring type, it is determined based on the pressure of different material systems.

The specific requirements vary by specialty; it is generally around 1 meter of static pressure
