Add, after 2.3.103, the following new definitions:
2.3.103.1
semi-automatic normally open valve with latch
a valve which is closed when energized. When power is removed the valve will not open
automatically and must be manually reset
2.3.103.2
normally open valve, automatic
a valve which is open when not electrically energized and when power is removed the valve will
open automatically

11.103
Replace the second paragraph by the following:
Compliance is checked by connecting the normally closed (normally open) valve to the supply
at rated voltage, at room temperature and when mounted in the most unfavourable position
declared in Table 7.2, requirement 31, and with or without oil at the maximum working pressure
connected to the valve inlet, whichever is more unfavourable. The voltage is then slowly
reduced to 15 % of the minimum rated voltage. Before this value is reached, the valve shall
have closed (opened) automatically.
Add the following note at the end of the subclause:
The value of 15 % is based on the usual normally closed valves where remanence, friction and possible rest
currents due to control and signalling circuits can influence the closing force.
11.104.1
Replace “normally closed valves” with “normally closed, normally open and safety shutoff
valves of the automatic type”.

11.104.6
Delete the note.
11.104.8
Add, after “closing” the words “or opening in case of normally open valves”.

Replace item d) by the following:
d) if also declared as a semi-automatic valve, permanent blocking of the manual actuating
means shall be discouraged by suitable means; and
Suitable means may be: strong actuating force, button or handle protected by a cover, recessed button with close
tolerance with regard to enclosure.
Replace item e), by the following:
e) shall not be equipped with a means for holding it in the open position except for the manual
reset mechanism, if applicable.
