0.2.5 Unauthorized reconstruction and<br />
manufacture of spare parts<br />
Reconstruction or modification of the valve is only<br />
admissible after consultation with the manufacturer.<br />
Genuine spare parts and accessories authorized<br />
by the manufacturer serve to maintain safety. The<br />
use of other parts can annul all liability for the<br />
consequences.<br />
0.2.6 Inadmissible modes of operation<br />
The operational reliability of the valve supplied is<br />
only guaranteed when used as designated, as laid<br />
down in section 1.0 of the technical manual. The<br />
operating limits given on the identification plate and<br />
in the data sheet may not be exceeded under any<br />
circumstances.<br />
0.3 Transport and storage<br />
The universally recognized technical<br />
<br />
standards and the regulations<br />
regarding prevention of accidents<br />
have to be observed at all times when<br />
handling.<br />
0.3 Transport et stockage<br />
Lors de chaque manipulation,<br />
<br />
observer les normes techniques<br />
acceptées ainsi que toutes les<br />
mesures préventives contre les<br />
accidents.<br />
0.3.1 Transport<br />
The goods have to be carefully handled in order to<br />
prevent damage.<br />
The end flange caps supplied are to be fitted to the<br />
valve as applicable.<br />
0.3.2 Unpacking<br />
Having been unpacked the shipment is to be<br />
checked in respect of entirety and possible<br />
damage.<br />
0.3.3 Storage<br />
If the valve is not to be installed immediately<br />
following delivery, it must be properly stored.<br />
Storage should be in a dry room at a temperature<br />
as constant as possible.<br />
Storage over a longer period may necessitate<br />
individual moisture proof packaging. This is<br />
dependent on the local conditions.<br />
0.3.4 Return shipment<br />
If the return shipment is required, contact<br />
manufacturer at the address listed in 0.0 for<br />
specific instructions.<br />
The operator of valves used for aggressive or toxic<br />
media must ensure that these are well flushed and<br />
cleaned before being handed to the maintenance<br />
personnel. This is particularly important when<br />
returning to the manufacturer. Material Safety Data<br />
Sheets (MSDS) are required for authorization to<br />
return valves to the manufacturer.<br />

OPERATOR MANUAL<br />
1.0 VALVE FUNCTION<br />
The unique function of this option is to lock out the<br />
valve (prevent the operator from opening) when the<br />
process fluid is hot, preventing injury to the<br />
operator. The system requires an external thermal<br />
switch (Normally Closed type) wired to the valve to<br />
indicate when the process fluid temperature has<br />
exceeded the safe limit. A temperature of 120° F<br />
(49° C) maximum is recommended.<br />
2.0 VALVE OPERATION<br />
The valve is closed with a clockwise rotation of the<br />
handwheel, opened with a counterclockwise<br />
rotation of the handwheel. The Hot Lock Out<br />
Bonnet option prevents the valve from opening<br />
when the process fluid temperature reaches a<br />
predetermined point as measured by a thermal<br />
switch. When the thermal switch indicates that the<br />
process fluid is hot, the override switch will<br />
illuminate. The valve can be closed at all times, all<br />
temperatures. If the valve cannot be opened and<br />
the override switch is not illuminated, the operator<br />
should assume the process fluid is hot.<br />
3.0 VALVE OVERRIDE<br />
A valve override is standard on the Hot Lock Out<br />
Bonnet. It is located on the side of the housing and<br />
has a red indicator lamp with the word “HOT”<br />
engraved. When the process fluid is hot, the lamp<br />
is on. If the valve must be opened while the<br />
process fluid temperature is hot,<br />
depressing/holding down this switch and turning<br />
the handwheel counterclockwise will open the<br />
valve.<br />
<br />
Depressing the override switch permits opening the<br />
valve regardless of the process fluid temperature.<br />
Serious personal injury may result.<br />
<br />
Si on appuie sur l’interrupteur prioritaire, on peut<br />
ouvrir la vanne quelle que soit la température du<br />
fluide de traitement. Dans ce cas, des blessures<br />
graves peuvent s’ensuivre.
