The article recalls the author's experience working with a failure in a chilled-water distribution system. He was tasked to identify the required pressure within the terminal units of the piping branches. He and his fellow workers opened the control valves and found a fan coil. They also examined the terminals for the discharge-air temperature. They found out that the valve was installed without the diaphragm and orifice plate.
