    The double-valve thermostat may also regulate the flow of coolant to the carburettor: as long as the temperature of the coolant is relative low, the carburettor will be warmed up, so further speeding up the warming up of the engine. The wax used within the thermostat is specially manufactured for the purpose.

  5. Piping and plumbing fitting - Wikipedia

    Valves stop (or regulate) the flow of liquids or gases. They are categorized by application, such as isolation, throttling, and non-return. Isolation valves temporarily disconnect part of a piping system to allow maintenance or repair, for example. Isolation valves are typically left in either a fully open or closed position.

  6. Zone valve - Wikipedia

    In this way, applying power to the "open valve" terminal causes the motor to run until the valve is open while applying power at the "close valve" terminal causes the motor to run until the valve is closed. The motor is commonly powered from the same 24 volt ac power source that is used for the rest of the control system.

  7. Globe valve - Wikipedia

    en.wikipedia.org/wiki/Globe_valve

    Globe valve. A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. [1] Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.

  8. Relief valve - Wikipedia

    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.

  9. Jacketed vessel - Wikipedia

    en.wikipedia.org/wiki/Jacketed_vessel

    In chemical engineering, a jacketed vessel is a container that is designed for controlling temperature of its contents, by using a cooling or heating "jacket" around the vessel through which a cooling or heating fluid is circulated.
