    In a typical depressurization system, the goal is typically reduce the pressure in the plant to less than 50% of the design pressure or to 7 barg, whichever is lower, within 15 minutes. [2] Disposal of blowdown fluids is generally to flare systems or, if safe to do so, non-fired blowdown drums. Blowdown may be strategically delayed by fire zone ...

  6. Pressure switch - Wikipedia

    en.wikipedia.org/wiki/Pressure_switch

    A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids.

  7. Earthquake valve - Wikipedia

    en.wikipedia.org/wiki/Earthquake_Valve

    An earthquake valve (or seismic valve) is an automatic method to shut off the low pressure regulated gas supply to a structure during a major earthquake and/or if a pipe is broken. These are applicable both to utility-supplied natural gas and to gas from liquefied petroleum gas (LPG).

  8. Push switch - Wikipedia

    en.wikipedia.org/wiki/Push_switch

    A push switch (button) is a momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated. An automatic mechanism (i.e. a spring ) returns the switch to its default position immediately afterwards, restoring the initial circuit condition.

  9. Adjustable pressure-limiting valve - Wikipedia

    en.wikipedia.org/wiki/Adjustable_pressure...

    An adjustable pressure-limiting valve (commonly abbreviated to APL valve, and also referred to as an expiratory valve, relief valve or spill valve) is a type of flow control valve used in anaesthesiology as part of a breathing system. It allows excess fresh gas flow and exhaled gases to leave the system while preventing ambient air from entering.
