  2. High-integrity pressure protection system - Wikipedia

    en.wikipedia.org/wiki/High-integrity_pressure...

    A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system is exceeded, thus preventing loss of containment through ...

    A relief valve DN25 on cooling water pipe from heat exchanger Schematic diagram of a conventional spring-loaded pressure relief valve. A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.

  5. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    Pressure regulator for domestic water supply. Outlet pressure is set with the blue handwheel and shown on the vertical scale. A water pressure regulating valve limits inflow by dynamically changing the valve opening so that when less pressure is on the outside, the valve opens up fully, and too much pressure on the outside causes the valve to shut.
