  2. Pilot-operated relief valve - Wikipedia

    en.wikipedia.org/wiki/Pilot-operated_relief_valve

    A separate actuator on the piping releases pressure in the line if it crosses a threshold. This releases the pressure on the back of the seal, causing the valve to open. The essential parts of a PORV are a pilot valve (or control pilot), a main valve, a pilot tube, the dome, a disc or piston, and a seat. The volume above the piston is called ...

  3. Valve seat - Wikipedia

    en.wikipedia.org/wiki/Valve_seat

    Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, [1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the ...

  4. Pilot valve - Wikipedia

    en.wikipedia.org/wiki/Pilot_valve

    Pilot valves are useful because they allow a small and easily operated feed to control a much higher pressure or higher flow feed, which would otherwise require a much larger force to operate; indeed, this is even useful when a solenoid is used to operate the valve. Pilot valves are often used in critical applications (e.g., emergency and SIS ...

  5. Angle seat piston valve - Wikipedia

    en.wikipedia.org/wiki/Angle_seat_piston_valve

    Pneumatic valves are operated by a pilot medium under pressure, usually compressed air but also oil or water. The valve is equipped with a pneumatic actuator supplied by a three-way solenoid valve. The pressure of the pilot medium enters the actuator cylinder and acts on the piston, which allows the seal to open or to close through the stem.

  6. Valve job - Wikipedia

    en.wikipedia.org/wiki/Valve_job

    A valve job is the colloquial term for resurfacing the mating surfaces of the poppet valves and their respective valve seats that control the intake and exhaust of the air/fuel mixture in four stroke internal combustion engine, replacing valve oil seals, replacing any deficient valve springs, and otherwise bringing the components of a cylinder head up to manufacturer’s spec. [1] A ...

  7. Multi-seat valve - Wikipedia

    en.wikipedia.org/wiki/Multi-seat_Valve

    Multi-seat valve with pneumatic actuator. Multi-seat valves, or multi-port valves, are used to shut off or control complex liquid flows in sterile areas in the beverage and food industry as well as in the fine chemical and pharmaceutical industry. Multi-seat valves often replace combinations of several single-seated valves in aseptic processing.

    However, other professions that require skilled navigation, like bus drivers (3.11%) or pilots (4.57%), did not show a significantly different rate of Alzheimer's disease-related death. Such jobs ...

  9. Valve - Wikipedia

    en.wikipedia.org/wiki/Valve

    Pilot valves are valves which are used to control other valves. Pilot valves in the actuator lines control the supply of air or liquid going to the actuators. The fill valve in a toilet water tank is a liquid level-actuated valve. When a high water level is reached, a mechanism shuts the valve which fills the tank.
