Manual override, a mechanical device that allows the momentary or locking manual opening of normally closed valves or the closing of normally open valves, is available as a factory option on some models of the company’s Series 58, 20, and 70 solenoid valves. According to the manufacturer, there are a number of situations in which it may be necessary to actuate a single solenoid valve in an array of valves without disturbing the electrical sequencing or piping of these valves. The manual override option is built into the valve bodies and won’t affect the normal operation of the valves unless actuated in the case of power failure or some other similar circumstance.
