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:

  1. If most of the pressure drop is taken through the valve and the upstream pressure is
    constant, a linear characteristic will provide better control.

  2. If the piping and downstream equipment cause significant resistance to the system,
    equal percentage will provide better control.
