Spring loaded safety valve:
- For a spring-loaded safety valve, the pressure required to lift the valve (also known as the cracking pressure) is less than the pressure required to open it fully (also known as the popping pressure).
- This is because the spring exerts a force that opposes the pressure of the fluid acting on the valve. In order to overcome the spring force and lift the valve, the fluid pressure must be slightly higher than the spring force.
- Once the valve is lifted, the fluid pressure can then act on a larger area of the valve, which increases the force on the valve and causes it to open fully.
Therefore, the pressure required to lift the valve is less than the pressure required to open it fully
