[QUOTE="Doc Hudson, post: 171251, member: 1607"] Welcome to the forum Campsie. These valves have been manufactured by Honeywell for a long time, I am sure the flow rates have been calculated into the design process. What is your application that makes you feel a normally open valve is preferred to a normally closed valve? From the literature Honeywell provide "The V4043B normally open model is particularly applicable to control of solid fuel systems, since it will always fail-safe in the event of a power failure."
