0.2.5 Unauthorized reconstruction and manufacture of spare parts Reconstruction or modification of the valve is only admissible after consultation with the manufacturer. Genuine spare parts and accessories authorized by the manufacturer serve to maintain safety. The use of other parts can annul all liability for the consequences. 0.2.6 Inadmissible modes of operation The operational reliability of the valve supplied is only guaranteed when used as designated, as laid down in section 1.0 of the technical manual. The operating limits given on the identification plate and in the data sheet may not be exceeded under any circumstances. 0.3 Transport and storage The universally recognized technical standards and the regulations regarding prevention of accidents have to be observed at all times when handling. 0.3 Transport et stockage Lors de chaque manipulation, observer les normes techniques acceptées ainsi que toutes les mesures préventives contre les accidents. 0.3.1 Transport The goods have to be carefully handled in order to prevent damage. The end flange caps supplied are to be fitted to the valve as applicable. 0.3.2 Unpacking Having been unpacked the shipment is to be checked in respect of entirety and possible damage. 0.3.3 Storage If the valve is not to be installed immediately following delivery, it must be properly stored. Storage should be in a dry room at a temperature as constant as possible. Storage over a longer period may necessitate individual moisture proof packaging. This is dependent on the local conditions. 0.3.4 Return shipment If the return shipment is required, contact manufacturer at the address listed in 0.0 for specific instructions. The operator of valves used for aggressive or toxic media must ensure that these are well flushed and cleaned before being handed to the maintenance personnel. This is particularly important when returning to the manufacturer. Material Safety Data Sheets (MSDS) are required for authorization to return valves to the manufacturer. 2 OPERATOR MANUAL 1.0 VALVE FUNCTION The unique function of this option is to lock out the valve (prevent the operator from opening) when the process fluid is hot, preventing injury to the operator. The system requires an external thermal switch (Normally Closed type) wired to the valve to indicate when the process fluid temperature has exceeded the safe limit. A temperature of 120° F (49° C) maximum is recommended. 2.0 VALVE OPERATION The valve is closed with a clockwise rotation of the handwheel, opened with a counterclockwise rotation of the handwheel. The Hot Lock Out Bonnet option prevents the valve from opening when the process fluid temperature reaches a predetermined point as measured by a thermal switch. When the thermal switch indicates that the process fluid is hot, the override switch will illuminate. The valve can be closed at all times, all temperatures. If the valve cannot be opened and the override switch is not illuminated, the operator should assume the process fluid is hot. 3.0 VALVE OVERRIDE A valve override is standard on the Hot Lock Out Bonnet. It is located on the side of the housing and has a red indicator lamp with the word “HOT” engraved. When the process fluid is hot, the lamp is on. If the valve must be opened while the process fluid temperature is hot, depressing/holding down this switch and turning the handwheel counterclockwise will open the valve. Depressing the override switch permits opening the valve regardless of the process fluid temperature. Serious personal injury may result. Si on appuie sur l’interrupteur prioritaire, on peut ouvrir la vanne quelle que soit la température du fluide de traitement. Dans ce cas, des blessures graves peuvent s’ensuivre.
TECHNICAL/SERVICE MANUAL 1.0 INSTALLATION WELD END VALVES Weld end valves for schedule 10 and heavier pipe require bonnet and diaphragm removal prior to welding in line. See Section 3.4, steps 1-3, 5-9. 2.0mm and lighter pipe and tubing may be welded with automatic equipment without removing the diaphragm. Manual welding requires diaphragm removal for all pipe wall thickness. VANNES D’EXTRÉMITÉ A SOUDER Avant de procéder à une soudure en ligne sur des conduites de catégorie 10 ou plus épaisses, enlever le chapeau et le diaphragme des vannes d’extrémité. Voir section 3.4, étapes 1-3, 5-9. Les conduites de 2 mm ou plus minces peuvent être soudées au moyen d’un appareil automatique sans enlever le diaphragme. En cas de soudure manuelle, enlever le diaphragme quelle que soit l’épaisseur de paroi des conduites. 1.0.1 <strong>Pure</strong>-<strong>Flo</strong> ® diaphragm valves may be installed in any orientation. To ensure optimum draining in horizontal pipelines, the valve should be installed so that one of the drain marks on either valve end is precisely in the 12 o’clock position. Note: According to good practice, horizontal pipework should be sloped toward the drain point to ensure optimum draining. 1.0.2 1.0.2 CAUTION! Prior to pressurization (with valve partially open), tighten the bonnet bolts in a crisscross pattern in accordance with Table 1. Re-tightening 24 hours after the system reaches operating temperature and pressure is recommended. If leakage occurs at the body/diaphragm seating area, immediately depressurize system and tighten bonnet bolts as noted above. If leakage continues, diaphragm replacement is required. See Section 3.4. ATTENTION ! Avant toute pressurisation (la vanne étant partiellement ouverte), serrer alternativement les boulons diagonalement opposés du chapeau (voir tableau 1). Il est recommandé de resserrer les boulons 24 heures après que le système ait atteint la température et la pression de fonctionnement. En cas de fuite du joint entre le boîtier et le diaphragme, dépressuriser immédiatement le système et serrer les boulons du chapeau comme indiqué ci-dessus. Si les fuites persistent, remplacer le diaphragme. Voir section 3.4. 3 1.0.3 The unit is to be wired according to Fig. 5. Maximum wire size is 14 AWG, the recommended size is 16 AWG. The wire should be stripped a length of .23" (6mm). All AC inputs must be protected via a circuit breaker or fusible link not to exceed 20 Amps. All DC inputs must be protected via a circuit breaker or fusible link not to exceed 10 Amps. 1.0.4 For models with switch outputs, the switch settings are factory set. If field adjustments are required (Fig. 6.): OPEN Switch: Fully open the valve. Turn the open potentiometer on the circuit board clockwise until the green open LED on the circuit board is illuminated. Continue to turn the potentiometer an additional 1/4 turn. CLOSE Switch: Fully close the valve. Turn the close potentiometer on the circuit board clockwise until the red closed LED on the circuit board is illuminated. Continue to turn the potentiometer an additional 1/4 turn. Note that on the LBP Solid State version, the circuit board has a three-way switch (PNP - 2 wire - NPN). This switch must be properly positioned, before power is applied, dependent on the desired electrical equivalent output. 1.0.5 ITT recommends that the required external thermal switch be set to trip at 120° F (49° C). It must be a normally closed switch. The switch should be located close to the steam source or in the piping system where accurate readings will be obtained. The switch must not be in a location where the steam can deadhead resulting in false readings. 1.0.6 The travel stop (see Fig. 1), is factory set and should not require adjustment at time of installation. However, if adjustment is required, see Section 2.3. 1.0.7 1.0.7 CAUTION! Do not attempt to close the valve when the bonnet is removed from the body and the travel stop nut is not in position for models with a potentiometer gear. Potential damage to the potentiometer may result. ATTENTION ! Sur les modèles avec engrenage pour potentiomètre, ne pas essayer de fermer la vanne si le chapeau du boîtier a été enlevé et l’écrou limiteur de course n’est pas en place, car le potentiomètre risquerait d’être endommagé.
