Do Steam Valves Fail Open Or Closed at Lilly Eng blog

Do Steam Valves Fail Open Or Closed. On a kimray high pressure control valve, there is a position indicator attached to the stem that shows if the valve is open or closed. When the batch contents reached the required reaction temperature, steam was shut off and chilled water was sent to the heat exchanger to control the reactor. Deciding between a fail open valve and a fail close valve is an important step in protecting your system. Fail open means a valve would open at a loss of signal or power. If the valve is under no pressure, and the arrow on the position indicator is. Choosing the right option is dictated by the specific application and which failure mode will best. These types of valves require air pressure to stay closed. Under a power outage, the source of the air pressure would be lost and the valve would “fail” open. Once the required air pressure is gone, the valve will naturally open. Whether steam valves should fail open or closed depends on the application and the safety requirements of the system. A pressure reducing valve lowers the input pressure of a fluid to a desired lower output pressure. A fail close valve, as the name suggests, is engineered to automatically return to a closed position in the absence of power, effectively.
