What are the Applications of Quick Opening Valve Characteristics ? in oil and gas industries.
Quick Opening Valve
• Used for frequent on-off service.
• Used for processes where “instantly” large flow is needed (i.e. safety systems or
cooling water systems).
Two rules of thumb for choosing the right flow characteristic:
If most of the pressure drop is taken through the valve and the upstream pressure is
constant, a linear characteristic will provide better control.
If the piping and downstream equipment cause significant resistance to the system,
equal percentage will provide better control.
